Squid 1.0.1 panics my machine

Hello,

Within the last 10 days squid managed to crash the machine
(www-cache.uni-siegen.de).
Squid runs on a SparcStation 5, Solaris 2.4.

I have no idea about the source of the problem, I had never *such*
problems with Squid befor.
Below is what I found in the syslog.
I couldn't find anything special in the Squid logfiles
and Squid dumped no core file.

Any ideas?
