[squid-users] squid 2.5STABLE2 dies at midnight

Twice in the last two days my Squid (2.5.STABLE2-20030509) died at about midnight, it appears that a restart was attempted, but it failed. I have a cron job scheduled to do a log rotate at that time. Below is an extract from the CACHE.LOG file from last night.
Any ideas/suggestions?
