The FD limit is 16384. During the day I see peak utilization around 8,000. At night the utilization is less than 1,000. During the four hours the CPU rises from <10% to 100% the FD utilization stays less than 1,000.
Again, I have not seen this problem under load, only while squid is relatively idle. It usually starts around 10:00 PM, and is not related to log rotation. # uname -a Linux pxsrv03 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:48 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux # /opt/squid/bin/squid -v Squid Cache: Version 3.3.5-20130607-r12573 configure options: '--prefix=/opt/squid' '--with-maxfd=16384' '--with-pthreads' '--enable-storeio=aufs' '--enable-removal-policies=heap' '--disable-external-acl-helpers' '--disable-ipv6' --enable-ltdl-convenience Mike Mitchell ________________________________________ On 11/06/2013 10:42:32 -0700, Loïc BLOT wrote: > Hello mike, > please look at the number of system file descriptors opened, the squid > limit and the squid user limit.
