Does anybody know how much memory should an asp.net website consume? My new asp.net website seems to consume a lot of memory from the hosting server.
note that up until now we haven't used any type of caching.
I have really tried to Google it but only articles about how to troubleshoot memory issues come up. Before I start to troubleshoot, I would like to know if my web site's memory usage is really abnormal or not.
So it is an asp.net mvc 2 website that runs on IIS 7.5 in production. I guess normal memory usage depends upon traffic, so here are the numbers of an average day:
300 unique visitor
400 visits
3000 page views
I would be really happy to get some idea how much is the normal memory usage for this traffic. Also I would be curious to know how memory usage normally increases with traffic growth.
The application pool randomly shuts down. I am assuming this is due to Rapid Fail Protection and errors are occuring that are triggering it. However... there are no errors being reported in the event logs. So my next inclination is to think of the possibilities of a memory leak. How do you test for memory leaks on a website running locally?
View 2 RepliesI am building an asp.net application, using II6 on windows server 2003 (vps hosting).
I am confronted with an error I didn't receive on my development machine (windows 7, iis 7.5, 64 bit).
When my wcf service tries launching my query running against a local sql server this is the error I receive:
Memory gates checking failed because the free memory (43732992 bytes) is less than 5% of total memory. As a result, the service will not be available for incoming requests. To resolve this, either reduce the load on the machine or adjust the value of minFreeMemoryPercentageToActivateService on the serviceHostingEnvironment config element.
I have both VS 2005 and 2008 installed on my machine. 2005 is fine. For 2008, literally any asp.net project I try to create gets this eror. I try stepping into the code, and the error occurs apparently before anything that I can trap is loaded. There is no information written to the event log. I have tried this with a "Hello World" webpage with nothing else going on. Seems unique to my Windows Server 2003 machine.

I am maintaining C# .NET code written by somebody else, I get following exception few times,Attempted to read or write protected memory. This is often an indication that other memory is corruptThe code structure where I get the above exception is somethign like this,- it is using ref variables in following sequence,Variable-1 and variable-2 are local variables in App1, - App1: func1() which passes these variables reference to func2(), - App1: func2() passes same variables reference via .net remoting to another application (App2).-App2: does the same passes same received reference to another call 2 times.- The execption is occured while returning from App2.
(App1:func1(ref Var1, ref Var2) --> App1:func2(ref Var1, ref Var2) <---App1 .net remoting to App2--> App2:func3(ref Var1, ref Var2)--> App2:func4(ref Var1, ref Var2)-->variables getting updated and function returned to original caller)
My doubts are ,1. Is passing reference variables in such chain is correct? will it cause such exeption? Does .net support ref variable call directly?
Environment.WorkingSet incorrectly reports the memory usage for a web site that runs on Windows 2003 Server.(OS Vers: Microsoft Windows NT 5.2.3790 Service Pack 2, .NET Vers: 2.0.50727.3607)
It reports memory as Working Set(Physical Mem.): 1952 MB (2047468061).
Same web site runs locally on Windows Vista with a Working Set(Physical Mem.): 49 MB (51924992).
I have limited access to the server and support is so limited.
so i have computed the total memory by traversing with VirtualQuery.
Total of pages with state: MEM_FREE is 1300 MB.
(I guess server have 4 GBs of RAM and PAE is not enabled, max user mode virtual address is 0x7fff0000.)
So, i know working set is not only about virtual memory. But, is it normal to have such a high working set while its very low on another machine?

I have a memory leak somewhere that I cant find. Every few days my server will crash, and just before that I log a ton of SQL errors stating that it is "out of memory".
I cant find it anywhere, all of my connections are being disposed like so:
[Code]....
Then I call the connection from my pages like so:[Code]....
That is all pretty straight forward. The connection is disposed because it is implementing the USING clause. I am opening the connection in my connection manager class, and not where it is being utilized?Or, could the problem be in the below method I am using to populate a SqlDataReader:[Code]....
Now, at first it appears as though this could be the problem because the Connection isn't part of a USING clause, however doesn't the 'Data.CommandBehavior.CloseConnection' pretty much do the same thing. This makes sure that the connection is closed when the reader is closed, right? Here is how I call that above reader from my login page code behind:[Code]....
So the DataReader will get closed even without the .Close() because it is in the USING, and the connection should get closed because I specified it in the ExecuteReader paramters right?
I have a memory issue on my websites and am trying to get to the bottom of it. I have downloaded the 14 day trial of ANTS Memory Profiler and have been playing with it to get a grip of what it's telling me. In the memory options on the timeline, I can see Bytes in All Heaps and Private Bytes etc but I am not sure which ones I should be focusing on to see where the memory spikes and doesn't go back down.I am profiling a ASP.NET website using ASP.NET 2.0.
View 1 RepliesI am facing problem to consume rss feeds, I found several articles on How to consume RSS feeds, they helped me to some extened but I didn't get info for what exactly i am looking. My problem is: I tried to consume feeds from these two [URL]
I've used this code to get the feeds info XmlTextReader readerSport = new XmlTextReader [URL]
DataSet dsSport = new DataSet();
dsSport.Clear();
dsSport.ReadXml(readerSport);
for both the feed dataset have same 8 tables but with diffrent names, and if i write the xml using the folloing code
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("[URL]");
//xmlDoc.Load("[URL]");
xmlDoc.Save(Server.MapPath("~/sowetan.xml"));
after observing the genrated xml, both the xml have diffrent structure.
1. What information required to display the feed content?
2. if we have diffrent structures for the genrated xml how can we write a single transform method?
3. Is all the 8 tables data required for displayingrss content, In most article i found they've used only for table 3
4. I want to open the feed content on my webpage, how it can be done.
Is there a clean way i can consume WCF RIA Services within an MVC 2 Application?
View 1 RepliesI'm currently working on an ASP.NET Website where I want to retrieve data from an RSS feed. I can easily retrieve the data I want and get it to show in i.e. a Repeater control.My problem is, that the blog (Wordpress) that I'm getting the RSS from uses for linebreaks which I obviously can't use in HTML. I need to replace these with a <br /> tag.
SyndicationFeed myFeed = SyndicationFeed.Load(XmlReader.Create("urltofeed/"));
IEnumerable<SyndicationItem> items = myFeed.Items;

i have not worked with XML in a while can someone post the syntax needed to build and save an xml node structure that resembles that of a tree structure that is created by a recursive function.
basically i have a recursive function that saves data found an a page(url) and then follows each URL found on that page recursivley and does the same to it. to audit this i want an output as a xml file to disk so i can see how it is doing its recursion and parsing.
the code i have is below. please add to it the needed xml calls needed to create a xml structure like the one i show below. (please include the full name space so i can see where the objects i need in .net are for this.)
page1.htm has 2 links on it:
<a href=page1_1.htm>
<a href=page1_2.htm>
page1_1.htm has 2 links on it
<a href=page1_1_a.htm> (this then will have some links also)
<a href=page1_1_b.htm> (this then will have no more links on it - dead end)
the xml should do something like this:
<node url=page1.htm>
...<node url=page1_1_a.htm>
...... <node url="xxx.htm"/>
...... <node url="yyy.htm".>
... </node>
...<node url=page1_1_b.htm />
</node>

We have a web application providing a service using a simple REST interface (GET/POST methods) and returning results in JSON format.
A client wants to use the service from an ASP application (I assume ASP.NET) and asks for example code.
Is there any standard/widely-acceptable procedure for consuming JSON based web services from an ASP.NET application? I'm not familiar with the .NET framework, but can work my way through C#.
