We are migrating from squid-nt to squid on a linux box, using 2.5 stable 7 compiled with async io. Unfortunately, due to the holidays, we've been unable to subject the new linux proxy to any significant load since re-compiling with async io.
We have experienced one apparent lockup of squid so far, with only 30 clients online, and minimal use. The squid process was using 200Mb RAM, and 99.9% CPU, and refusing connections. It did not respond to a shutdown, and processes had to be killed off. We have also seen a few "queue congestion" messages in cache.log. I read one thread which suggested too many threads may result in these messages. Are there other methods to determine the optiumum number of threads? Compile options are as follows: Squid Cache: Version 2.5.STABLE7 configure options: --quiet --sysconfdir=/etc/squid -- localstatedir=/var --enable-delay-pools --enable-snmp --enable- async-io=30 --disable-wccp --disable-ident-lookups --enable- auth=ntlm,basic --enable-removal-policies Cache is on three 9Gb 10k RPM scsi drives, using aufs. System is a dual P3/733 with 768Mb running linux 2.4.22-37 (Mandrake 9.2) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Shawn Wright, I.T. Manager Shawnigan Lake School http://www.sls.bc.ca [EMAIL PROTECTED]
