Yep, it was zabbix for me as well. Killed the CPU on all my filers. You will have to go through and remove a bunch of checks

Thanks for the response. Yes, we're polling with Zabbix (and generating snmp traps).
So I'll shut those down for a while, and see if that helps.

The first thing that caught my eye was the snmpd, any chance you set up new SNMP polling from monitoring stations that is querying the disks over and over? If you can, turn off SNMP for a short bit to see if it goes away.

On the off chance - I'm having trouble with a filer. I can't ssh to it reliably (at all, mostly).
I'm pretty sure that's correlated with some high CPU load - my system console has it 'spiked' at >95% for the last 24h, and that's much higher than 'normal'.
What i'm not sure of is quite what's causing it - the filer is busy, but not abnormally so.
The only thing I can think of that _might_ have changed it, is api calls (qtree-list, get-file-info) - I've recently started doing quota snmp trap enrichment. (but thats 'every few minutes' at most).
But otherwise - I'm not sure what might be causing sshd to stall, and if there's a way to 'kick' it?
This is a 7 mode filer, on 8.2.1
I've got a case open, but would appreciate any further insight on how to track a high CPU-causing ssh to not respond type issue.
I'm pretty sure a failover/failback will do the trick, but that'll have to wait until the weekend - I'd like not to if I can manage it.
My current ps list looks like:

That seems pretty busy for a 4cpu system...
Thanks and regards, Ed.
