deadlock

I'm using a 3rd party tool, which uses a 4th party plugin. Occasionally, the tool will hang when launched. Looking at the stack traces, I can see a few threads are waiting on WaitForSingleObject, and my bet is that they're blocking each other. Some of the threads start at the 3rt party tool, and some at the 4th party plugin.

What I'd like to do is file the most detailed complaint to the 3rd party tool vendor, assuming it's its fault (I don't trust their local support to get those details themselves). For that, I'd like to:

Find out what are the synchronization objects currently waited on
Find out who has created those synchronization objects

Tools currently at hand are VS2005, WinDbg and Process Explorer. OS is Window 7 64 bit. Any suggestions?

Will logging debugging incur a performance hit if I don't turn debugging on?

On a Cisco device, I know that enabling debugging can incur a performance hit since debugging has such a high priority on the CPU. I know that to log debugging, you have to set logging up to the debugging level (logging buffered 4096 debugging, for example) and also enable debugging on some feature… >>> More
