I've found that the problem are the semaphores left hanging by the aborted
PVM processes. The quickest way to kill all of the semaphores being owned by
the user is:
ipcs -s |awk '{if ($5=="'$LOGNAME'") {system("ipcrm -s " $2)}}'
The command must be used with precaution.
Thanks to the people who mailed me suggestions.
