I found out how to backtrace the core files from httpd crash due to SSLSessionCache, and here is the output of the backtrace from Sun Studio Debugger
Any help with this backtrace to find out if this is due to a misconfiguration, or a bug in the software would be appreciated:
dbx /opt/apache/bin/httpd /var/core/core.httpd.2372
For information about new features see `help changes'
To remove this message, put `dbxenv suppress_startup_message 7.5' in your .dbxrc
