w3wp memory usage

Last night I noticed a bunch of our web apps were getting out of memory
exceptions. I checked task manager on the server and the w3wp.exe process
had eaten up about 780 megs of memory. I did an IIS reset and it has solved
(temporarily probably) the issue. Memory usage dropped to about 50 megs or
so. This morning its up to 180megs. Can I tell what apps within asp.net
are using that memory?Hi, Jeremy.

You'd do well to run Windbg with the SOS debugging extensions.
That'll give you a good idea of what's consuming what.
