Weird double squid process

I am running squid 2.2stable 4 on Linux redhat
redhat-release-6.0-1
kernel 2.2.12-20

I logrotate every night at like 4 am, stop the squid, rotate, start the squid.

Somehow the squid tried to start the squid process twice. I include the
cache.log files. Maybe any of you have an explanation for that...

Thanks
Evelyn

Now this is how the cache log ends before logrotate:
