w3wp.exe Problem memory growing: asp.net 1.1 on Windows Server 2003

Hello Everyone,

I have a problem of this type:

The iis pool process w3wp.exe on running a
Asp.net 1.1 steadily increases memory until come over
1G (bringing the process to a situation of crash).


Specifically:


1) The application asp.net 1.1 ran fine on IIS 5.0


2) I moved the application to a Windows Server 2003 with iis 6.0


3) I have tried to search for Memory Leak with the tools of analysis
Memory, at the moment I have not found anything strange.


4) To save from the crashes I configured
The application pool by disabling the "Recycle worker processes (
Minutes) and enabling the "Recycle worker processes at following
times"
A reboot daily, and a "Maximed used Memory" to 1G.


I hope I have been clear enough in making the point of
Situation.
I expect that the process "w3wp.exe" remains constant on 250Mb/
300Mb.
How can I fix this growing problem of memory
I think it unusual?
Any advice would be welcome:)


Thanks,

Lorenzo Zuffa

How are you measuring memory usage?

A memory leak can be seen by watch Perfmon:Process:Private Bytes. You
should see it increase for a while as the process & caches "warm up" and
then hit equilibrium. A memleak itself will not cause a crash until
allocations start failing which typically requires memory usage to be >1.5GB
(or more depending on allocation sizes).

Memory fragmentation can be seen by watching both Private Bytes &
Process:Virtual Memory Allocated. The curves should more or less track
together. If they diverge then you are seeing fragmentation (which again
can be caused by a leak).

If you are getting a crash, you can use IISState or Debug Diag to get a
thread stack and we can take a look and see what is happening.
