[Pdns-users] Odd random crashes

[Jeroen Wunnink]

Once every few days our pdns instance will crash with the following 
type of error:

Dec 27 14:07:10 ns1 pdns[14875]: Got a signal 11, attempting to print trace:

This is pdns 2.9.18 (the .19 gives us issues with the fancy records) 
on a Fedora C2 machine with the latest legacy updates on it.
When it crashes out like this, the guardian process will die too, we 
tried both a self compiled version (guardian doesn't crash, but it 
doesn't start a new working server process then), and the pdns-static 
rpm (it completely dies)

These crashes are very random, happening once every 3-5 days, 
sometimes in the middle of the day, sometimes at 4am in the morning (joy ;)
It's only on this server though, our other pdns servers are fine. 
Does anyone have an idea what might cause this ?
