System.OutofMemoryException - Session

Hi

I have an application running on a cluster that's constantly throwing an OutOfMemoryException with the following message
"Unable to serialize the session state. Please note that non-serializable objects or MarshalByRef objects are not permitted when session state mode is 'StateServer' or 'SQLServer'.

In this instance, session state mode is set to 'StateServer' and the only object being stored in the session is a dataset (which is serializable)..

Anyone have any ideas

Thanks!for starters, what does your dataset contain?
any funky stuff in the dataset or just basic types?

i'm puzzled that an outofmemoryexception would contain a serialization
string

System.OutOfMemoryException in asp.net web application

Hi,

We are getting System.OutOfMemoryException exception in an asp.net
application hosted on IIS.
The problem is popping up randomly once every few days.The web server needs
to be restarted as users keep on getting 'Server Application Unavailable'
otherwise.

Could anyone please tell abt the possible causes and solution for this.

Cheers,
JitenOhboy... it could be due to any number of things, without knowing more about
your app it would be very hard to tell what is wrong.
You can wire up your app to capture more info on unhandled exceptions, and
you can also use AdPlus in "hang" mode to take a dump of the W3WP.exe or
ASP_NET.EXE process.

One of the most common culprits is inproc session management. If you store a
lot of data in session variables, consider switching to outproc sessions.

there are a couple causes:

1) too large session
2) memory "leak" of unmanaged resources. common if you use com object or
don't manage sql connections
3) faulty caching.
