Howdy...
I came home to find my workstation thrashing - errors are appended to this
message. Kerneld was consuming over 50meg of memory, so I bounced it,
which seems to have cleared the problem up.
Overmind is a P90, 2.0.32 and is fairly well synced with Hamm. Modutils
is 2.1.55-4. Current uptime is almost 13 days. The machine was idle at
the time.
I've been unsubscribed from linux-kernel since before 2.0.32 came out,
so I don't know if this problem has been discussed over there. I just
resubscribed.
