¿Anybody knows how to avoid this problem? If I don't reboot xymon it
crash.

Hmm. If it's growing truly without limit there's something unusual going
on; I'd take the memory allocation error later on at face value.

Can you provide any additional details? Do you have an unusual workload or
ulimits on the xymon user? Or a large number of host inserts/removals?
What OS are you running?
