problems running squid

I have been running squid on a sparc10 (solaris 2.5.1) for several months,
and all has been well until this morning. It stopped running, and now I
cannot get it to restart. It starts normally, runs for a few seconds, and
then spontaneously shutsdown. I cannot see any errors, so I am including
the cache.log: Can anyone offer any suggestions?
