[squid-users] SQUID CRASHING - HELP!!!

HI all!
I have installed squid-2.5.STABLE3 on a RH 8.0/2.4.20-custom kernel/WCCP
patch/ P4/ 1 GB RAM/ 30 GB SCSI cache_dir system. I am using diskd.

I have compiled squid with:

./configure --enable-poll --enable-linux-netfilter --enable-snmp
--enable-storeio="aufs,diskd,ufs" --enable-removal-policies="heap,lru"

My squid runs happily for a few hours and crashes ... I am giving all
useful info below for your reference. Please let me know what could be
causing it.
Squid seems to be taking 99% CPU even after several hours since it has
crashed. If you notice diskd has disappeared from the ps list...so I
suspect it may be related to the disk.
