If it was an assertion failure, or FATAL event, or expception error, or
transaction ERROR there should be at least one line above these ones you
quoted which explains the problem.

If there is no such lines then we can assume its a segmentation fault
and you need to seek down a core file (if any) which was produced. The
error details will be in there.

If its regularly every 2 hours, I would look at your cron settings.
There may be some cronjob restarting or reconfiguring Squid every 2 hrs.

Another alternative is resource limits. If it takes more than 2hrs for
rock to load the cache index and the oom killer process of the kernel
kills the "resource intensive" Squid worker on or before completion you
would also see this type of behaviour.
