[Xymon] xymond crashing! -- Please help!

[Matt Vander Werf]

See below for a snippet from the xymonlaunch.log log file from starting up
to crashing to trying to restart itself to crashing some more.

Looking through the xymonlaunch log, it looks like this kind of pattern
shows up quite a few other times, dating back to November last year. But it
always seemed to resolve itself after a good while.

Not sure how long it will take to resolve itself this time (if it resolves
itself at all).

Any guidance is appreciated and let me know if there's anything I can do or
provide to help figure out this issue!

Thanks!!
