Rotate the logs files ?
cache.log, access.log, and the cache_swap_log.

This means it didn't need to remove any thing from the cache_swap_log
(your machines doing it on the run), you will notice in you
/usr/local/squid/logs/ dir that there will be the cache.log and
access.log with .0 to .WHAT_EVER_YOU_SPECIFIED_IN_THE_SQUID.CONF
These files ending in numbers can be deleted if you like, or analysed and
then deleted.

Yeah, thats what the cache.log is for, debugging as well.

See Above there should be .0 files in the logs directory

yep sure can.
Why don't you change the last bit to rm /usr/local/squid/logs/*.0
It would be safer.
