Amos, thanks for the links. I've looked at the mailing list and the open bugs, and could not find something similar to what I see, with the 10 minutes period. We're using a customized version of Squid 2.4 STABLE6, and it's not in my power to upgrade it to any later version... It runs on FreeBSD 6.2-RELEASE-p9 amd64 servers. I know I need some profiling/debugging information to determine where CPU spends its cycles, but on these servers most usual tools are either absent or not working very well: There's no 'oprofile' for FreeBSD, 'pmcstat' fails to run (no lib?), 'gprof' does not give info beyond parseConfigFile() even in my custom profiling-enabled version with -N, 'gdb' does not recognize debug info, and 'strace' is not installed. I've found 'truss' command to be working and traced system calls made by the squid process, trying to recognize some patterns -- noticed that during CPU load spike write() sometimes returns EPIPE, 'Broken pipe'. Does my version (2.4 STABLE6) ring any bells?
Sorry, 2.4 was ancient history when I joined the project. All I know about it is the list of features added that release.
Amos -- Please be using Current Stable Squid 2.7.STABLE7 or 3.0.STABLE20 Current Beta Squid 3.1.0.15
