ASP.NET application pooling issue
Posted on 2007-03-23
We have a problem with one of our websites server application pools restarting after every few minutes. The actual error message we are receiving in system logs is: A worker process with process ID of **serving application pool** has requested a recycle because it reached its virtual memory limit....
After further investigation using IIS debugger, we traced the problem to a dll called mscorwks.dll located in the Microsoft framework folder (v2.0.50727) , and found that there is a memory leak.
We are running .NET framework 2 on a multiprocessor server running Windows Server 2003 (Web Edition). The server uses 4 application pools though all other application pools are unaffected as they are running ASP code.
Can anyone help?
mscorwks.dll is responsible for 390.55 MBytes worth of outstanding allocations. The following are the top 2 memory consuming functions:
mscorwks!EEVirtualAlloc+104: 386.56 MBytes worth of outstanding allocations.
mscorwks!EEHeapAlloc+12d: 3.97 MBytes worth of outstanding allocations.
