Yep, 2 disks each of 1Tb in a mirror.

In the past days I have replaced the disks with brand new and excluded them
from the list of possible root causes :)

Have you done any ZFS tuning on the system? I find that the FreeBSD
ZFSTuningGuide page suggests tuning only for i386. Am I right to assume
that I don't need any tuning for amd64, which is my case?

Also is it normal that is I get 5.2Gb usage in ARC on a 8Gb system (not
really sure)?

Btw, after removing all ZFS snapshots today (more than a 1k) the system is
still running (not something I can say for the past few days where I've
seen multiple reboots a day).. But it's still early to say that the
snapshots might be causing this :)

Thanks again,
Marin
