Getting Request Timed Out Error When Uploading Large Files?
Oct 6, 2010
We have page that allows the users to upload documents (multiple). When the upload takes a long time - either due to the size of the files or due to slow upload speeds - we get a exception saying "Request timed out".
We found that the exception is thrown as soon as the upload is complete. So we have modified the executionTimeout config entry to 6000 secs. But this error still shows up consistently. We are running IIS6, .net 3.5 sp1 (asp .net 2.0).
Update.I'm able to reproduce this issue with relatively small files (multiple files with total of 75MB)
I use file upload control.........and below this there is upload button which include programming to upload file.........
It is working fine for file size of less than 2mb but when i pick file of 5 mb(say) and i click on file upload button or any other button then outcome is
Internet Explorer cannot display the webpage
I placed break point on upload button but control doesn't go their..........
I have a thread class which makes a web request. After 20-30 urls request, its throwing exception: System.Web.HttpException: Request timed out. My code is below where it is throwing exception:
I am getting this ajax timeout error.I am using updatepanel and update progress. Locally am not getting this error but after hosting this error is coming and the page is not navigating to the next page to show the result.
I tried most of the solutions eplained like below,
What is better way to large upload file. using a web service or in application itself. If in application, how can we check that files is to upload. actually i dont want user to wait for complete uploading, when it starts uploading user will get response of uploaded and uploading will be done in backgroud. I am not sure this type of task can be done in webservice also so that user doesnot need to wait for complete uploading. and one more query which event fires when the page redirects to another page. Is it Page_UnLoad or Dispose.
I've got an ASP.NET web application (utilizing WebForms) and am using Uploadify to handle uploading large files. This is done by posting the file to an HttpHandler.
Example of code (simplified for demonstration purposes):
$(".uploadify").uploadify({[CODE]....
the progress bar being displayed doesn't actually reflect the progress of the upload, and shows the upload as being complete long before the file is actually uploaded. Therefore, the user interface effectively appears like it is doing nothing while the progress bar stays at 100%, until the file is complete.
In some cases, the upload simply fails after reaching 100%, with the OnComplete event never getting fired, almost like the response from the HttpHandler is getting lost in transit, even though the file is saved.I've tried both Flajaxian and SWFUpload, and experienced similar issues with the progress bar being completely out of sync with actual upload progress, indicating completion well before the upload was actually complete.
This problem is not apparent when testing locally, or with small files (typically under a few megabytes) as these tend to upload fairly quickly and there's little or no lag between the file being uploaded and the progress bar completing.Is there any way of using a Flash upload solution (such as Uploadify) with an ASP.NET web application and have the progress bar better represent the actual progress of the upload?
Update: Eventually, I gave up trying to use a flash based uploader as they seemed a bit too awkward, especially the progress bar, which didn't represent the actual progress of the upload at all. Replaced this with Brettle NeatUpload instead which works much better.
Is there such a thing as an optimum chunk size for processing large files? I have an upload service (WCF) which is used to accept file uploads ranging from several hundred megabytes.
I've experimented with 4KB, 8KB through to 1MB chunk sizes. Bigger chunk sizes is good for performance (faster processing) but it comes at the cost of memory.
So, is there way to work out the optimum chunk size at the moment of uploading files. How would one go about doing such calculations? Would it be a combination of available memory and the client, CPU and network bandwidth which determines the optimum size?
EDIT: Probably should mention that the client app will be in silverlight.
i want to check my fileuploas size . if bigger then 2mbm error message will popup, this is my some of my code
If file_newimage.HasFile = True Then Dim ext As String ext = System.IO.Path.GetExtension(file_newimage.FileName).ToString If ext <> ".jpg" And ext <> ".png" And ext <> ".bmp" And ext <> ".jpeg" Then MessageUser("Photo uploaded must be in .jpg/.png/.bmp/.gif or .jpeg format") Else If file_newimage.PostedFile.ContentLength > 2097000.0 Then
[Code]....
but when i input image 12MB, just to check my coding my page went "Page cant be displayed" ...
I'm using a web form that allows users to upload media files. The code works great on small to medium size files, but I've found that if a file is really big(like bigger than 15MB), the user will get a 404 error. Currently I'm using the code below to handle the file. Does .NET provide another way to handle larger files?
When I run the selected file and press upload image files the following error:

code with windows application and it works in a good way and files uploaded to server successfully using text box control and open file dialog,but when I tried it with upload control on Asp.net application it doesn't work and gives error : Could not find file .......this is my code in windows application under button click FileInfo toUpload = new FileInfo(this.txtFile.Text); FtpWebRequest request = (FtpWebRequest)WebRequest.Create(this.txtAddress.Text + "/" + toUpload.Name ); request.Method = WebRequestMethods.Ftp.UploadFile;
have a web application which will allow me to upload files to my web folder. I have used the following code for uploading files (VB) on click of BUTTON UPLOAD
If FileUpload1.HasFile Then Try FileUpload1.SaveAs(Server.MapPath("/UPLOADS/" & FileUpload1.FileName))
While i am Uploading Some Video Files from my asp.net website(C#) for the first time, i foud some error which i am furnishing here under
"Access to the path 'D:inetpubvhostsdemon4netsalt.comhttpdocsStudy MaterialVideo+1' is denied."
Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access to the path 'D:inetpubvhostsdemon4netsalt.comhttpdocsStudy MaterialVideo+1' is denied.ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
i am planning to save my files in side the "
Study MaterialVideo+1, Study MaterialVideo+2, etc.. " Folders
We have a WCF service self-hosted in a Windows Service. Right now we're experiencing a really strange behavior with it, which is that every 23 hours, approximately, the service raises an exception for every call made to it with the following error: Server was unable to process request. ---> The request channel timed out while waiting for a reply after 00:01:00. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout.---> The HTTP request to [URL]has exceeded the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout.---> The operation has timed out. The duration of the failure is between 4 and 6 minutes and, without touching anything at all, the service then goes out of the failure and the following responses are ok, for the next 23 hours, and then, again the error.
As pointed above, the WCF service is self-hosted in a Windows Service, installed on a Windows 2008 Server OS. The clients calling the service are two different Asp.NET web services, one running on the same server and the other on a virtual server in a production environment. Both clients have presented the same issue. The configuration of the complete environment is this: Phone calls are received in an IVR system (let's say node 1), which calls a web service (node 2) that retrieves some information about the customer calling. Once the customer approves the operation, the IVR calls the web service (node 2), which relays the call to the WCF Service (node 3) to process a credit operation. The WCF then makes a TCPIP socket operation through a VPN connection to another entity (node 4). That communication lasts between 3 and 10 seconds, is registered in a persistent database and then is sent back in the same path to the customer (node 3, 2 and 1). This platform processes about 2,000 transactions a day, 24/7, except for the ones failing with the timeout. The reason to have the transaction relayed to a second service is for security purposes. The amount of data exchanged in each call is about 200 or 300 bytes.
I've already tried most of the workarounds posted right here in stackoverflow ([http://stackoverflow.com/questions/981475/wcf-timeout-exception-detailed-investigation][1]) and the ones appearing there and some others found in google. The error is still persistent. The TCPIP socket operations are logged to a text file, and found no issues there with the response times from the external entity. The largest time was 9 seconds. Also, a database operations trace has been logged and did not show any performance issues either. The concurrency mode of the service is set to ConcurrencyMode.Multiple and, before going into production we made an stress test with ten clients making iterative calls over 2 hours, processing the wcf service about 30k transactions with no signs of performance impact. However, I already discarded a concurrency issue because the average time between transactions is one minute, and the largest one lasts for 9 seconds approximately. Besides, all other transactions complete successfully, independently of the load on the service.
I cannot increase the timeout of one minute given the fact that the service is for executing ecommerce operations and in fact there's nothing really taking more than a few seconds to complete. This are the facts, and I hope you guys could come up with something I haven't already tried yet. Please have in mind at the time of answering that this is a critical mission service, and the changes or configurations possible to apply in a production environment are very limited.
I am experiencing the following page error when trying to use the FileUpload control on my web page to upload files larger than 3MB or so. The error is as follows:"Problem loading page The connection was reset The connection to the server was reset while the page was loading.
* The site could be temporarily unavailable or too busy. Try again in a few moments.
* If you are unable to load any pages, check your computer's network connection.
* If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web."I suspect this may be due to a timout issue. If so, how can I increase the timeout period for this control / process? I am coding in VB.NET.
i have a web application which which proccesses some request on some data that client selects, when the client selects more than 20 objects and clicks on proceed the client recieves this error, because the server takes a long time to process, however if the records are less and hence a timely response is recieved, no such error comes?
i have increased the sessiontimeout as well as set the
I've checked many threads about this but I'm not sure how to fix this:When I try to upload a 33 mb file while debuggin, control directly falls into application_endrequest even when I've a breakpoint set to first line in application_beginrequest in my global.asax.cs. I can see the page in non-postback case.My maxRequestEntityAllowed is set to 400000, and in web.config I got
<httpRuntime maxRequestLength="1024000"/>
What else do I need to fix? I can upload a 25mb file btw.platform: IIS7, Windows 7 64 bit, .NET framework 2.0, integrated pipeline
In a page, I have 4 fileupload controls. The filesize should be under 3mb. When submitting the form, I checked the filesize. If any of the uploaded filesize is higher than 3mb than I warn the user. Hovever, in this case, other successful file uploads are lost. So user would have to reselect intended files. I want all the files to be uploaded when all of them are validated successfully. How can I retain selected files even if there is a validation error?
have developed a Asp.net application which uploads data from Excell Sheet and then Inserts those data after doing several Checks to the Mysql data base.The Issue which Iam facing is that when Iam uplading lage amount of data at a time say around that 10000, the application crashes and gives the Unable to Open connection to server Error.The same app works well 1000-2000 data.
Not sure what's going on with this procedure, im kind of new at dynamic DB programming. As of right now if i click a button that triggers the execution of this stored procedure the page says the connection has been timed out..despite other stored procedures working flawlessly.
