Hi,
        I hope someone else has run into this problem before. It goes something
like this :

        After about 2 weeks of uptime, the root server doesn't have enough
swap space to start up another login session (an X session particularly).
I ran monitor, and the swap space was 98-99% utilized.  And there wasn't
anything running!!!  So after a little while of poking around, I gave up
and rebooted.  Then I ran monitor again, and the swap utilization was down to
67%.

        The best that I can figure is that for some reason, when some processes
die, init can't regain all/or any of that processes alocated swap.  Is there
any sort of a cron job that will go out and look for defunct process and
try to regain its swap allocation ? This has also happened on another 340
cluster.  Does anyone have any suggestions ?

        We're running X11R3 on hp9000/340 workstations.

        Thanks in advance,
        greg
