Not sure right now, but to mitigate your problem for now, you can install
the Windows Resource Manager (WSRM) which can monitor things like processor
usage and either set a max limit on the processor usage per process (eg. use
only max 50% of the processor) or it can recycle applications that hit a
predefined peak usage (eg. when processor hits 80%, recycle this app).
Have a look here
http://www.microsoft.com/windowsserv...oads/wsrm.mspx for more
information and to download.
Addressing the problem itself, have you run performance monitor and had a
look at requests queued, requests aborted, and other similar counters to see
if some rogue process is being started and never quite ending. Are you
adding any processes to the threadpool for execution?

We have a larger ASP.NET application that is running on 3 identical
servers, (Network Load balanced) with Windows 2003
On average the servers has 250 active sessions each. They serve about the
same number of requests per second.
Now, after running for sometime, we are loosing processor time, (avg %
processor time for the asp.net) is slowly rising, and after a while (days)
the processor queue length gets higher and higher, and finally the server
will stop serving requests.
We reboot the server automatically, and its back to zero again, starting
to climb.
We cant see any obvious errors in the application it self, neither does
eat up the memory. Its just affecting processor performance.
Any tips?
