Greetings,
Today we experienced an F330 pegging at 100% CPU. netstat and nfsstat didn't reviel anything eye popping, and so I'm asking for suggestions as to what might cause this?
I would guess that a network interface shouldn't be capable of causing this, but I'll let you tell me....

Check for really big directories, ie dirs with tens of thousands of files.

Was it creating a snapshot, or deleting a gigantic file?

Not to my knowledge. Plus, this went on for several minutes. Snapshots usually take 20-30 seconds? No large files since none of our client machines can handle > 2GB files.

Disk scrubbing? RAID reconstruction? Nothing in /etc/messages that might provide a hint? Did it just go away on its own after a while? I've noticed that a deep "find" or a "du" can keep the CPU very busy, without an obvious spike in NFS ops.
