Hey All,
I''m having some issues with a snv_126 file server running on an HP
ML370 G6
server with an Adaptec Raid Card (31605). The server has the rpool, plus two
raidz2 data pools (one is 1.5TB and 1.0TB respectively). I have been using
e-sata to backup the pools to a pool that contains 3x 1.5 Tb drives every
week. This has all worked great for the last 4 or so months.
Starting last week, the machine would panic and reboot when attempting to
perform a backup. This week, the machine has been randomly rebooting every
3-15 hours (with or without backup pool attached), complaining of:
(#pf Page fault) rp=ffffff0010568eb0 addr=30 occurred in module "zfs"
due to
a NULL pointer dereference
I use cron to perform a scrub of all pools every night, and there have been
no errors what so ever.
Below is the output from mdb $C on the core dump:
