How's this?

This is a CentOS-6 64bit server with 8G RAM and two Ethernet cards - one
internal and one external. iptables is used to redirect outbound tcp
port 80/443 (on internal network) onto squid port 3129/3127
respectively. I've removed the two ACLs I had and they haven't caused
any change, so they are not related to the problem
access.log does not show any entries (the crash occurs before they can
write I guess) and the cache.log shows the following whenever I "telnet
1.2.3.4 443" (I've appended the cache.log from the start, through the
crash to the next start)
