Hey list,
when I set SSLSessionCache to shm:/opt/apache/logs/ssl_scache(512000) or
to shmcb:/opt/apache/logs/ssl_scache(512000) httpd childs dump core
with this output to the error_log when LogLevel is set to debug :

error (10), possible coredump in /opt/apache

When running ipcs -sa to display shared memory usage as root, I get no output.
With my old apache 1.3 using mod_ssl and MM I have output when running ipcs -sa

To fix my problem, I have set SSLSessionCache to use dbm, that way I
get no errors but it is documented that dbm can suffer instability
under heavy load ...

Anyone can help fixing this ? any suggestions ? I built apache with
Sun Studio 11 under Solaris 8 with mod_authnz_ldap/openldap in 64bit
with these flags to the compiler -fast -xarch=v9b -xcode=pic32 , I
then compiled mod_perl and mod_evasive using apxs

Thank you
Yannick
