Issues with FlowCleaner on a spam server.
Hi my friends I have a big issue that I still cannot track what is causing that my server stop working. I have a spam gateway running: spamassassin clamavis amavis apache+mailgraph postfix bacula client apcupsd client My server is running freebsd 8.0-p2 AMD64. Raid-1.

My server can work for a month, each weekend I update the ports and upgrade my packages, spamd rules every month are updated. No issue here, suddenly after a month or 4-5 weeks the server stop working, amavisd stop doing the job, I can access the server via ssh and see the issue. This is the 4th time that happens. My IDLE goes to 50%, when I start debugging I see a process called FlowCleaner eating 1 CPU. Always got the PID 20, looks like a internal process, I have been searching info about this process but not to much info. I cannot kill this process, I can restart clamd, spamd, apache, bacula, but amavisd is stuck. If I send a shutdown -r now won't work, my server just hang-up, if I press the power button won't work to. I have to do a cold reboot, I don't have other choice. I have read logs but don't see any issue (maillog, console, all, message). One thing to mention, is that every time this happen, my server fan's are working more faster that usual, the first day I detect this I create a batch that send every 5 minutes the core temperature using freebsd coretemp.ko module. Avg. I got 40'c for each core: dev.cpu.0.temperature: 42.0C dev.cpu.1.temperature: 41.0C I search around on Intel site and this chip max temp. is 70'c, I had never seen this number on my emails, the biggest number had been 54'c and this appear before my server got crazy yesterday: dev.cpu.0.temperature: 53.0C dev.cpu.1.temperature: 49.0C Something is causing this, a spam attack, memory leak mmm I had not seen my server use the whole 4GB ever. My friends, what do u you recommend to me to track this? Any input will be very appreciated, I got 1 month to track this before this happen again, thanks! ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
