I have a system that is being problematic, I suspect but I cannot say for
sure it is maybe related to ZFS as I have a fairly large ZFS pool on the
machine. The system will just lock up, local console does not respond to
the keyboard, num lock still changes the led on the keyboard, the system
still responds to pings but you cannot ssh to the unit. The behaviour is
random the system can be running for 50 days plus with no issues then
suddenly it enters this state, the error logs do not show anything.
--As for the rest, it is mine.
Where is your swap located? I've seen similar on a ZFS system with swap on
ZFS, when running low on RAM. If that's the case, you can either put in
more RAM (so you don't need to use swap) or move swap to a dedicated
disk/partition, that's not under ZFS control.
