4.2 System Tuning

[John Bass]

Since I didn't spot any upload/download/uucp/network activity in the ps
listing is smells like a floating rs232 input talking to itself or a flakey
board in the system. A floating rs232 line talking to itself also leaves
a trail of aborted logins in /usr/adm/wtmp (or it's eqiv on 4.2) ... and
simular tracks in the process accounting data ... both point to the bad line.
If it's some other board in the system ... time to plug your own metrics into
the interrupt handlers and figure out where they are coming from ...

Have fun ...
