Hi I am a beginner.
Making a file system filter driver in Win2k .
It work great after a few miniutes . When I close all running
applications (IE explorer windows) then mouse icon changes to the wait
icon. Seem like a lot of processing is going on. But I do not see so
many my debug prints showing such high processing.Though I can move the
mouse but I can do nothing because of the wait sign and ultimately have
to reboot.
I have Driver verifier on and do not get any memory bug check.
So my question is what all conditions or commands can I check for this
hanging in Windbg? Also What all settings I can do in driver verifier &
windbg for more conditions checking ?
Eg. In terms of dead lock , memory over use, memory corruption etc.
Any Ideas will be very helpfull.
I tried !deadlock but it gives
“No export deadlock found”
So what does this mean??
Regards,
Anurag
Hi,
For debugging hangs there are three commands that I usually go to
immediately:
-
!stacks: this gives a summary of all of the threads in the system. This
is a quick way to figure out which threads are blocked and if you had
anything to do with it
-
!locks -v: shows the state of all of the ERESOURCES in the system
-
!process 0 7: this is extremely verbose output of every process and every
thread. This takes a while to go through, so it’s usually a last resort
According to the debugger docs !deadlock is only available in XP and later,
which would explain the “No export found” error.
HTH,

Good tips. For me, so far I’ve tended to reach for !process 0 7 as first
port of call, and watch all those stacks scolling past. Funny thing , sounds
mad, but I’ve tended to have a couple of candidate hypotheses by time
!process has finished, just on the basis of what I have seen in the stacks
scrolling past. Maybe I just been lucky!
