Hello All,
I've been able to consistantly reproduce a GPF on Apache service shutdown using Openssl 0.9.6i, and Apache 2.0.44.
Swapping to an older version of Openssl (0.9.6g) resolved the GPF.
To reproduce, simply download and build OpenSSL 0.9.6i and Apache 2.0.44. Be sure to configure ssl to use the shmcb ssl session caching. Launch apache as a service and browse to the server using SSL. Then try to stop the apache service. During shutdown, Apache will GPF.
Oddly, if you don't browse to the webserver using SSL, Apache will not GPF on shutdown.
If it helps, the call stack looks as follows:

The error in log_error_core is: [Mon Mar 03 12:43:04 2003] [warn] (OS 6)The handle is invalid. : Failed to acquire global mutex lock.
Is this a known issue? Is there something that I'm missing? Other than changing from DBM to SHMCB, I have stock conf files.
Thanks in Advance,
