System freezes after 20-30 days on the regular
-
Did you check the monitoring graphs/ That can often show show some resource leak.
-
@stephenw10
States hovers around 400 with filter states up to around 1100
MBUF has a max of 1M and hovers around 6000-7000
Memory hovers around 91% free
CPU sits around 300 processes -
Nothing ramping up like a resource leak?
-
@stephenw10 Just checked these again. No change in their numbers. Still all minimal.
-
Hmm, sure seems like a leak of some sort if it's happening that regularly.
What NICs is it using? You might check the sysctl stats for something exhausting there.
-
@stephenw10 Thought I would just go the whole output of system devices. This is a Sophos SG450 Rev1 box. Lots of Intel devices.

Hmm, well those should be fine.
Those do provide a lot of stats via the sysctls so there might be something there.
-
@stephenw10 you want the whole "-a" lot? Or is there a qualifier you would use that might be a slightly smaller list? Seems there is potentially sensitive info in that file. Can I send it to you direct?
-
Nope I'd start with the mac stats so like:
sysctl dev.ix.0.mac_statsThere may be something in the iflib values. Though to be honest nothing there should really stop it responding entirely. You might be able to see some value growing where it shouldn't. The reported errors perhaps.

Nope everything there looks good.
Though if you were to see something there it would be probably be just before it stops responding. Even then NIC/connection issues shouldn't really stop a system responding at the console.
Migh just have to wait until it happens again and try ctl+t. If it really doesn't respond even to that it starts to look like a hardware issue.
-
@stephenw10 cheers. We shall wait!
