Hi,

ENV: .Net 1.1, VS 2003, Windows Server 2003 SP1

We are seeing some issues with the Gen 2 heap unexpectledly increasing over
a lengthy period in an ASP.Net application. To troubleshoot this we've been
using the 1.1 CLR profiler, this shows allocations, but I am unable to find
out which objects are being retained in Gen 2. How can I do this?

Many thanks,
Stuart

I think you can do it with the Sos.dll debugger extensions.

Yes, you can. You can run the following command in SOS to get that
info:

!dumpheap -gen 2 -stat
