Hello,
I am currently experiencing some really nasty stability problems today. It all started with a power outage this morning. When the power came back I booted up the server and ran zpool scrub on the array. Later in the day I check the status on the scrub and could not ssh into the box. I power cycle the machine and ssh back in to the machine. About 10 minute later ssh disconnects and the machine stops responding.
Next I plug my monitor into the box and watch what was going on. Like before around the 10 minute mark I see a kernel panic happen. The message states that it could not write the crash dump to the disk :\
I then powered cycle the machine once it came back up I then rebooted it. The reboot takes a very long time waiting to process to shutdown. It gets to the syncing of the nodes, spiting out a bunch of 4s, 2s and 1s and then says time out. Next the screen says that it is emptying the buffer and a bunch of numbers are written to the screen. After about 2-5min of this I get another kernel panic.
Tried the above again and the same result. :\
Any help trying to diagnosis the issue?
Notes:
Thanks,

Notes:
- Up to today my systems has been stable with no crashes what so ever.
- I am running with on 2GB of ram (which i know is sub optimal, but the machine is really only used to store and watch tv shows)
- I also read that upgrading to 8.2 stable fixes a lot of issues with ZFS, not sure if this will fix my problem
Thanks,
