[squid-users] Squid process crash every day, why?

Hi, I am new to the mailing list and have the following issue:

Our squid crash every night between 01:00 and 02:00 CET.

Logrotation this:

Mar 15 03:10:17 srv-app-904 run-parts(/etc/cron.daily)[4280]: finished logrotate

And here the interesting part from cache.log (with minus in the memory usage????):
