w3wp crashs and memory leakage problems

[Gaël]

Hi everybody!

I have a really big problem with ASP.NET application. I noticed that the
w3wp.exe memory size, increase with the time and the use of my website. When
it raise a certain value, w3wp crashes and restart just after. My
application is on a WebServer2003.

So I have to resolve 2 problem :
-Why the memory size of the w3wp increase non stop.
- Why the w3wp crashes (in the case where there is no link between those
problem)

I did the test with another site with just some button and a datatable on it
and I have the same problem. (Knowing that may be a memory leakage I have
track all possibility of object that may not be destroyed, but alls are
disposed)

SO if anybody have a suggestion, he is welcome!

Is w3wp crashing or recycling? You can configure an application pool to
recycle at a certain memory threshold, so this could be happening. Or it
could simply be exhauting all the memory available on the box.

To work out where your memory problem is, grab a memory profiliy utility
like the CLR profiler or .NET Memory Profiler from
