[squid-users] Squid/Linux crash - please help

Hi,

I have got squid running on HP ML530 with two Xeon 3.0 GHz, 8GB Mem, and 8x36 Gb hard disk. Six disks have been dedicated for Cache and using reiserfs filesystem and mounted as /cache1 to /cache6.

OS - Red Hat 8.0 , Kernel 2.4.20
squid Cache: Version 2.5.STABLE4
configure options: --enable-async-io --enable-gnuregex --enable-kill-parent-hack --enable-cachemgr-hostname
( haven't set up cachengr yet)

Yesterday the system crashed. Other than ping response, it was not doing anything. I couldn't login into the console. I had to cold boot the server in order to bring up the server. I checked the logs, and I can't see anything unusual or wrong. Squid is working fine after the cold boot.

The server is not under heavy load, ( probably less than one tenth of the load we are planning put to the box) . I don't know where to start and look at the problem. Please help. I am attaching the output of the top command and my squid.conf file.

Thanks in advance for the help.

Mathew
