Alright, I've executed the following on the server. Do I need to restart Kamailio or anything for it to take effect?
```` echo "1" > /proc/sys/kernel/core_uses_pid ````
I've checked the memory monitor for the time around the last crash (+/- 6 hours), but there was no noticable change in memory usage before or after the crash.
You can see the graph here: http://i.imgur.com/3v3usoJ.png
The red line is approximate when the crash happened.
