System.OutOfMemory and System.Web.HttpException

[shil]

Hi all, not sure if I'm posting in the right group.

I'm having a strange issue with my website. At our company we have a
load balanced servers. One server is working fine for all the web
pages but on the other server two of the web pages are throughing the
following exceptions. The source code is an exact copy on both. I
have
even compared the IIS settings on both servers, which are even. Can
any one help me with this?


Error on one page:
--------------------------------
The state information is invalid for this page and might be
corrupted.
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.Web.HttpException: The state information is
invalid for this page and might be corrupted.


Error on the other page:
--------------------------------
Server error in '[website]' Application.
Exception of type 'System.OutOfMemoryException' was thrown.
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.OutOfMemoryException: Exception of type
'System.OutOfMemoryException' was thrown.

Hi Shil,

You reported 2 problems:

1. Corrupt State info for a Web Page.
2. Out Of Memory Exception

Resolution for "Corrupt State info":

It seems the Machine Keys of ALL Server machines do not match. For more on
this go to: http://support.microsoft.com/default.aspx/kb/323744


Resolution for "Out of Memory":

This is very tricky to debug and for this i will need more info. Can you
please check the system log of the machine and send me the detailed error
report.


Hope this helps.

regards,
Joy

Hello joy,

Hi Shil,

2. Out Of Memory Exception

detailed error report.

Also, the out-of-memory exception might have triggered a ASP.NET worker process
recycle, which (if the Machine keys aren't set to a fixed value) will generate
new keys, and cause the next request to throw a corrupt state exception.

The out of memory exception is one you need to fix. Memoryleaks that make
the ASP.NET workerprocess so large that it will recycle due to memory starvation
is a huge performance problem.

Thanks to both of your for your time.
Today the server that was raising error is behaving fine but the other
web server that was fine yestday is giving "Corrupt state info"
error.
The microsoft link that was provided is for ASP.NET 1.0 version. I'm
using 2.0 version.
Also, how can I tell which process is causing the memory leaks?

Hi Shil,

For memory leak in your code you need to use a Profiler to find out the
erring code. One good Profiler is ANTS Profiler by Red-Gate.
