Re: watchdog timeout for pwait/rc.shutdown
2011/7/14 Subbsd sub...@gmail.com: Hi Tell me please, is it possible to change the behavior of shutdown sequence to avoid work of kill process (or increase timeout). Тot always process can not react to signals and stop - for example, heavy MySQL server databases or databases/redis - can not keep up with 30 seconds to correct shutdown. In my example noSQL product - redis holds a 10 GB RAM memory and when stop it just did not have time to reset the state to disk when i stop process or jail with redis. As result ive have in /var/db/redis dump.tmp.XX - broken DB about ~3 Gb instead of 10 GB. Waiting for PIDS: 47924 30 second watchdog timeout expired. Shutdown terminated. Thu Jul 14 16:24:30 MSD 2011 Killed PS: I may be mistaken but I think this problem did not exist before PS2: i have RELENG_8 and HEAD version of FreeBSD PS3: Thanks in advance I have roughly the same problem when I shut down my laptop, squid takes at least 1 minute to shut down, so if I shutdown or restart without stopping squid first, then all my processes just get killed rather than shutdown cleanly by their rc script. An option to vary/disable the timeout would be welcome.

An option to vary/disable the timeout would be welcome. squid by default waits 30 seconds before closing to give time to clients to close their connections. This is a very conservative value needed for big proxies. If you're using squid just to serve the local machine or a not so big network you can greatly lower this value, setting it to 5 or 10 seconds, or even less and have squid take much less time to stop. the configuration directive you should look at is shutdown_lifetime -- Guido Falsi m...@madpilot.net ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
