As of a few weeks back I started getting very slow shutdowns ...
Anyone else seeing this or got some color on the problem ?
here's what seems to be happening:
shutdown ..
network goes offline
ntpd asks for an update (looks like it traps the kill -15 ..
and stays up trying to clean up )
named times out .. and gets error .. wont shutdown cleanly
(it has received a kill -15 which it has trapped)
named waits trying to clean up - cannot clean up coz network is down.
ntpd finally exits (and stops nagging named)
delay of shutdown now about 4 mins .. .
eventually named gets killed harder harder (and finally exits)
