[squid-users] Squid crashing

I've been having problems with squid crashing, especially during busier
times. This is with RH 7.2 on s390.

Squid Cache: Version 2.5.STABLE3
configure options: s390-redhat-linux --prefix=/usr --exec-prefix=/usr

--enable-basic-auth-helpers --enable-ntlm-auth-helpers
--enable-external-acl-helpers

The samba is 2.2.8a.

Also, is the core written with uid/gid of user (squid?) or root? I
assume squid. I don't have a core now because the /var/log/squid/core/
was owned root:root, now it's squid:squid so if it happens again...
