ASP hang 21 Jul 2010 - 15:07
Hi

I'd be very grateful for any help with interpreting the following analysis from WinDbg. The problem is an ASP application hanging about once a day. The only solution is to manually recycle the application pool. The server is Windows 2003 and IIS6.

Many thanks in advance.

Here's the output:
