RE: Trouble with huge amount of State Server Sessions Timed out

Steven,

thank you for your answer. In fact, to my horror, I had to realize that
<compilation debug/> was set to true which I now changed to false.
As for your question regarding the server the application is hosted of a 2
processor xeon with 2 GB RAM and Windows 2003 Server. I checked IIS
Application Pool Settings and the only thing which is configured is “Recycle
worker process (in minutes)”. There are no settings configured for “Memory
recycling”. As I already mentioned there is almost always 1GB RAM available,
only for a couple of times when only 800MB were available. Recycling of the
process due to lack of memory should definitely not be a problem, at least
this is what I would have expected…

Greetings

Daniel
