[Xymon] xymond core dumping, not restarting correctly

[Clark, Sean]

Yeah, and I've had it crashing since 4.3.3 – updated to 4.3.7, still crashes about every 7-15 days, with a different host/test combo

Oddly, on only 1 of the 8 instances of xymon I have (I have tried a completely different server in that same instance) so now I am investigating my configs

Could be a bad link to the libredblack library?  Did you "make clean" before you built Xymon?

I've had xymond core dump on me twice now since updating to 4.3.7

It's dumping with:

And

I've tried it on two machines, to rule out any weird hardware/RAM issues, and it still happens – and when it crashes, a stale xymond stays, preventing it from auto restarting and binding to port 1984, making me have to go in, kill everything, remove the .chk file (as it has that out of bounds status message still in the chk file)

Makes for an irritating time – they were different host/test combinations causing the crash

Any ideas on what to do next? Is it just something like max_msg that is causing an Out of Bounds crash?
