Thanks, I will try it out.
Why does removing the chk file seem to fix it? Does it try to establish
old connections?

This happens when xymond has crashed and is restarting, but either some
of the old xymond_channel messages are still running (hanging on to a
shared memory segment or a semaphore), or the shared memory segments
were not cleaned up after the crash.
You can check with ipcs (as the xymon user) if there are any shared
memory segments lying around after all of the xymon tasks have exited.
I have a script to cleanup everything and restart Xymon - writing new
code may on rare occasions mean that xymond crashes :-) - feel free to
try this. If you're not on a Linux box, make sure the "ipcs -m" and
"ipcs -s" output has the shmid / semid in column 2. If not, adjust the
'awk' command to grab the correct column.
#!/bin/sh
if [ `id -u` != `id -u xymon` ]
then
echo "You must be the 'xymon' user to run this."
exit 1
fi
echo "Stopping Xymon"
~xymon/server/xymon.sh stop
sleep 2
if [ -f /var/run/xymon/xymond.pid ]
then
echo "Forcing kill of xymon process, PID `cat
/var/run/xymon/xymond.pid`"
kill -9 `cat /var/run/xymon/xymond.pid`
fi
echo "Cleaning up shared memory segments"
ipcs -s|grep "^0"|awk '{print $2}'|while read ID; do ipcrm -s $ID; done
echo "Cleaning up semaphores"
ipcs -m|grep "^0"|awk '{print $2}'|while read ID; do ipcrm -m $ID; done
