IIS resets my session variables [RESOLVED]

[mendhak]

Environment:

Windows 2003 SP1, IIS 6, .NET 1.1

Every once in a while, my session variables will get cleared and I couldn't view pages which depended upon session variable values. Obviously.

I thought this was a minor problem and set the session timeout to 60 minutes. Still, they would get cleared out inexplicably. Sometimes after 20 minutes, sometimes almost immediately.


I checked the event logs, and this is what I found:

Event Type: Warning
Event Source: W3SVC
Event Category: None
Event ID: 1011
Date: 6/1/2005
Time: 4:28:19 PM
User: N/A
Computer: MENDHAK
Description:
A process serving application pool 'DefaultAppPool' suffered a fatal communication error with the World Wide Web Publishing Service. The process id was '3264'. The data field contains the error number.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
Data:
0000: 8007006d

The link did not help at all.

As far as I understand, the App pool is crashing, and W3SVC seems to be restarting as a result of this. And this is as far as I got.

Tell me what to do next, or if you know the solution, please post!
