I sometime have shared memory problems and I clean them up with this command.

ipcrm `ipcs -o | perl -ne ' { m/^m\s+(\d+)\s+(\d+)\s+\S+\s+operator \
operator\s+(\d)$/; print "-m $1 " if ($2 eq 0 and $3 eq 0) }'

I am considering putting this in my cron to run on the weekend.  Checking
that amanda is not currently running.  If someone has any input about
doing this please let me know.
