The problem that prompted my question is reported in 
http://issues.apache.org/bugzilla/show_bug.cgi?id=29567

My problems with shared memory and mod_ssl (same problem as with 
mod_ldap - httpd refuses to start until the shared memory file is 
deleted first by hand) happens on RHEL3 with the following config set:

SSLSessionCache shm:/var/cache/ssl_gcache_data(524288)

If httpd dies uncleanly for any reason, I need to delete the file 
/var/cache/ssl_gcache_data by hand before httpd will start. A bit of a 
pain after a power failure.

Regards,
Graham
