Hi Folks,
Just wondering if anybody has any experience with xymongen hanging. I have
a large number of xymongen processes being kicked off sometime over the
weekend, unfortunately they are owned by apache and have a PPID of 1 so I
can?t tell how they were started. I?m presuming either xymoncmd but I can?t
see anything in the crontab for xymon or in tasks.cfg that would kick off
the snapshots and reporting processes.
These then sit for a very long time (> 24hrs) while trying to read a data
file from a specific server.

Every process (in the process list above) shows they have the same file
open as fd3, are they locking each other out or more to the point, should
they be?
Any ideas on where to look or what to do next?
