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.
