Hi,

I have 6 DNS caching Resolvers serving many thousands queries. Until recently all 6 were running Bind. As i've heard such great things about Unbound I decided to switch 3 of them to Unbound. So i've installed the latest Unbound 1.4.18 with Libevent and at first things seemed good but i've noticed at least 4 times a day Unbound is crashing with:

 kernel: pid 82301 (unbound), uid 59: exited on signal 11

I have a script that automatically restarts programs that should be running, so I didn't notice at first. I've tried tweaking loads of config options but nothing seems to make a difference. The servers aren't exactly that High spec:

FreeBSD 8.3
Dual Core CPU
4G Ram

However with Bind running the server is stable and if anything Bind uses a lot more CPU than Unbound for the same task. Can someone give me some idea's on what I can do to find out whats causing it to crash.

Regards

Phil
