The squid cache has reached it size limit and is being rebuilt to compensate... You could load squid in debug mode. There are a few debug mode options available for you... Just use squid -? to get a list of options. Alternatively, you can attach an strace session to squid to see exactly what it's doing. strace -p <pid of squid> > /var/log/squid.trace.out 2>&1 Tim Rainier Information Services, Kalsec, INC "John R. Van Lanen, Network Operations - TCCSA" <VANLANEN@xxxxxxxxx> 08/29/2005 03:29 PM To trainier@xxxxxxxxxx cc squid-users@xxxxxxxxxxxxxxx, VANLANEN@xxxxxxxxx Subject Re: dead squid, Still looking, If I do this, its a matter of hours and the same occurs again. What triggers the process that squid feels it needs to start again and add a new process, why did the old process die to begin with? In other words, what triggers the need to do this over and over again. When doing a squid status I only ever see 2 processes.
