That means there is a buffer overflow or writing at a wrong address.
I would suggest that you review the additional patches you apply to the stock Kamailio, because no similar crash has been reported to the project and such case wouldn't last long to show up in deployments, it is a high chance that the fault is coming from those additional patches.
Hi Daniel
Sorry for replying so late. I've been working on this and testing stability takes some days for every change.
First I realized that there was a big memory pressure in the systems by other processes and took care of that. It helped a bit but still not enough.
I had also a bottleneck in a shared redis-server where the dialog module was storing dialog and dialog profiles. Removing that shared redis-server and removing the dialog profiles has helped a lot with overall system stability. From several crashes per day to almost 0 crashes.
I'm not sure additional patches are the cause here. Anyway I think that now new coredumps, if they show up, will be more reliable because there are fewer external noise and the systems run smoother.
I'll continue testing and will let you know.
thanks,
Jon
