Just wondering if anyone can shed any light as to the crashes.
I saw that a few people have downloaded the log.
It is driving us crazy as prior to 2003 we had no problems at all.
Again the log file is http://temware.com/iisstate-log.zip
Looking at the log myself I see this in the thread that caused the crash.
WARNING: Frame IP not in any known module. Following frames may be wrong.
I've read some stuff about heap corruption and this message would seem to
indicate that.
I also saw that you would then have to debug the dump file.
Can anyone point me to the steps to do this?

I have also produced a log file before a crash and no threads contain this
warning.
So now I am going to do a log right before a crash and then a log when it
crashes to see what the thread was doing prior.

Thanks,
