freebsd stable - Jul 2011 - watchdog timeout for pwait/rc.shutdown

Hi

Tell me please, is it possible to change the behavior of shutdown
sequence to avoid work of kill process (or increase timeout).

?ot 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.

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

To increase the timeout, which is 30 seconds by default, just set
rcshutdown_timeout (in your rc.conf) to a value that works for you.

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.
