System hung (kernel bug ?)

[dea75]

Hi to all !

I have a serious problem with a production server on Freenas 8.0.3-4-(p1), seems identical to Ticket #1038.

Hardware:
HP Proliant 350 series, ECC RAM, redundant power supply, HP Smartarray RAID controller, USB pendrive for OS.
No hardware problems detected.

On Freenas 8.03-4-p1, after 12-15 uptime days system crash: "Fatal double fault" message.

Storage seems OK:
zpool status -x: "all pools are healthy"

Only one note: when the system crash, occurs approximately in the night (3 am).

Any idea ?

Very thanks

UPDATE:

14 hours testing: hardware all ok.

Only one possibility: under stress and low memory condition Freenas crash, is possible ? Now I try to increase memory...
(7 Gbyte ECC RAM are now installed).

Thanks

Luca

Did the memory bump work for you?

Also in 8.2 you can try to enable the Autotune option under System->Advanced.
