[Xymon] how to learn what is crashing my rrd handler?

I'm having difficulty with my RRD handlers crashing and leaving gaps in my databases.

I mentioned this back in April, 2014 but received no responses: http://lists.xymon.com/pipermail/xymon/2014-April/039547.html

Since that time, I stumbled across a client which was occasionally sending me empty messages of the "data" type. When I stopped that behavior, the behavior was corrected. The behavior has returned and I am not able to figure out how to find the cause.

I _suspect_ it is another client sending me empty messages, but how do I find it now that I have several hundred clients sending "data" messages?

Do things because you should, not just because you can.
