I am calling web service which takes very long time to execute due to which i get request timed out exception....
I hav kept my web method processing in try catch block....
even i have handled httpException....but it gives Request timed out exception..
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 have a webservice which works 100% fine on my developer machine. Where Web Service is installed on LOCALHOST on my developer machine,Then i went to my servers, I installed webservice on one server and map it with the server where the website is hosted, Then i tried accessing this service using BROWSER from my web server, it worked fine, That means the mapping was done perfect.Then i run my program on web server (website). It worked fine on page1, then on page2, but when i did the same and call same function on page3, It popped me any error of
View 4 RepliesA customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.

and result will be stored in a;
Please help me to encrypt this request using the X509 certificate. Am having a certificate with public key and with subject "My Calculator"and also decrypt the result with the private key "abcdef" and with subject "My Response"
I've got a web service on a server with valid IP and valid DNS entries. I'm using an asynchronous thread in a WPF .NET application to access methods from that web service. Under normal connection conditions, for almost all users, the connection and method works fine. Under a very specific condition - Verizon Aircard being used to connect, no VPN connection to the company through SSTP, on a PC with Forefront Client Security installed - the web service will return a "HTTP Error 400: Bad Request" error to the user. If the same user on the same PC connect their VPN connection, the method works flawlessly.
View 1 Repliesfor the past couple of days i am facing an issue where the first call from my ASP.NET 4 application (VS 2010 Web Site) hosted in IIS 7 to an XML web service is dead-slow. subsequent calls are fast until the AppDomain is restarted.
I have tried all solutions related to pre-generating the serializer assembly but nothing worked. Anyway THEN I was sure it is an IIS-only issue because if i consume the xml web service from a console .net application then all the calls are fast. its even fast from an ASP.NET web site NOT hosted in IIS instead running on the development server. SO clearly the problem is there only when my app is hosted in IIS.
I am trying to create a web service that can do the following functionality:
Request XML
[Code]....
How can I create web service to do this.
I want to use web service for periodic update request to server. It will use get & Post method.
Using post request I will use follwing URL. I will get this from some device.
[URL]
If request will come like this ... as URL contains 'update' so it should update & after parsing URL, will send reply in the form of URL.
I am trying to call webservice from my web application. The web application had integrated windows authentication. I've written custome principal class to do authorization. But when I give call to my web service with default credentials it gives me 'the request failed with http status 401 unauthorized.' error.
When I give call to my local webservice it is running fine (It also has integrated windows authentication) But when I add reference of same web service from QA server I am getting this error. Not sure what is happening. I also tried
WS.PreAuthenticate = false;
WS.Credentials = System.Net.CredentialCache.DefaultCredentials;
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:
httpReq.AllowAutoRedirect = false;
httpReq.KeepAlive = false;
httpReq.Headers.Add("Location", "");
httpReq.Timeout = this.HttpRequestTimeout;
httpRes = (HttpWebResponse)httpReq.GetResponse();
In last line : httpRes = (HttpWebResponse)httpReq.GetResponse(); it is throwing exception. "The remote server returned an error: (403) Forbidden."
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 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,

View 5 RepliesI know this has been asked umpteen times but i cant find an answer to my problem. Very simply, i have a webservice client which is trying to call a webservice. The webservice may take any time from 5mins to 30mins (or more) for downloading message data from pop3 server . However after 2mins i get the following error:
System.Net.WebException: The operation has timed-out
This is an issue with the webservice client timing out calling the webservice - as the underlying webservice still runs in the background
Sequence osf steps when the error occurs:
1.User logins with his credentials
2.Webservice client calls webservice to connect to pop3 server and download messages for that particular user.
Code in webservice for downloading data from pop3 server where the exception occurs
private string ReadOutput(bool bMultiline)
{
try
{
StreamReader srReader = new StreamReader(conn);
string strRet = srReader.ReadLine();
if (bMultiline)
{
// Example #4: Append new text to an existing file
string strLine = "";
while (true)
{
// In a multiline message the . indicates end of message
if (strLine == ".")
break;
// Relay will convert any line with just a . in it to ..
if (strLine == "..")
strLine = ".";
strRet += "
" + strLine;
}
}
return strRet;
}
catch (Exception e)
{
return null;
}
}
3.Exception is caught in webservice client while webservice continues to run.This exception occurs only when the user receives a large message may be above 1mb because i tested with 1MB msg file where i dint have any problem receiving or downloading from
pop3 server where as with 5 MB message file i got this exception .
After going through couple of forums i tested my luck by changing web.config in both webservice and webservice client where i set the attribute of httpruntime Execution timeout to 300 seconds with no success <httpRuntime
executionTimeout="300"></httpRuntime>.
I have this webservice client and webservice running on localmachine(OS-Windows Vista)
