What is the message?  How do you know it has anything to do with
swapping (and do you really mean swapped, as in a "0" Flags entry in
ps -fl, or just normal VM paging)?

I have seen wmgr (on 3.51) dump core when I do some bizarre things
with s_Suspd/s_Rsume/Suspd while windows are being created/deleted.
Maybe it's that?  But what you describe means that smgr went bye-
bye as well.  Look for a core file if in happens again.

It is very difficult for a program to find out whether it has been
swapped out.  Are you suspecting a system-wide problem with swap
errors?  If you ever run a program and immediately see "Killed"
instead, that probably means you are having I/O errors on the swap
device.  If you find a core file of wmgr, however, it's probably just
a bug in wmgr which almost certainly has nothing to do with paging.
On a standard system, wmgr's current directory is /etc/lddrv, so that
is the place to look for the core.
