clio is a 3/260 running SunOS 3.5; it's the nd server for 8 systems including bloch, a 3/50. One morning clio is running very slowly; the red blinky light on the back is going at about half speed, and vmstat shows roughly 50% cpu use even when everything else is quiet. Rebooting doesn't help. Looking at the output of 'ps auxw' doesn't show any unusual cpu hogs, which is quite puzzling -- where is the processor going? A look at 'nfsstat' shows a lot of nd traffic. Take a peek at the net with 'traffic' shows a lot of nd traffic, in particular between bloch and clio. Go upstairs to reboot bloch, and sure enough it's been dead since about midnight with the message "proc: table is full". Reboot bloch and everything is back to OK. Two questions: 1. Why didn't 'ps' show some process being very active serving nd requests? Which process(es) is (are) responsible for that? (biod didn't have an unusual amount of cpu usage). 2. What would cause an idle diskless machine to suddenly seize up with a "proc: table full" message? No one was signed on at the time.
