IIS hanging

Postby oferbar » Wed Nov 25, 2009 9:38 am

Hi,

Yesterday my IIS (on W2k3) stopped responding to any client requests.

After some investigation, it turned out to be the fault of the ynpagent DLL.

I don't know why, but if I unregister the DLL and restart IIS it works fine.

Here's the log file for the w3wp process, maybe this can help.

Thx

Unfortunately we cannot reproduce this problem in our environment. Fix is not impossible without the reproducible test-case. If you have some sample application which reproduces this issue please send it to support(at)yourkit.com.

Please also try version 5 of the profiler:

or at least upgrade to the latest 4.5.x series build 4.5.8:
