[Xymon] xymond core dumping (probably more for JC) Address out of bounds

[Clark, Sean]

Just as a side note --- disabling ghost matching (changed to drop) made it stop crashing — however this isn't a desirable setting

Subject: [Xymon] xymond core dumping (probably more for JC) Address out of bounds


JC – I installed the trunk version of xymond from terabithia – that fixed my core dump in all the deployments I had but one

This one, it’s core dumping every 1-2 minutes (same OS/libraries/kernels as all the other hosts – CentOS 5.10, latest kernel)



It dumps here:

#6  0x0805619c in do_message (msg=0x3099c5c8, origin=0x8073d92 “", can_respond=1) at xymond.c:4025

(        response = newstrbuffer(lastboardsize);  )



Here are all the symbols I could get:

Any ideas on what I should try next for this guy?
