[Pdns-users] re: 2.9.8 & signal 11

[Anthony Walker]

Hi

First, I must say well done and producing a great nameserver that can run on
mysql.
Its certainly going to make life much easier than having folks edit bind
files,
which often leads to mistakes.

I am getting the same error reported by Ole Gjerde.
Sometimes the server will stay up for 1 minute, sometimes 2 hours, then it
terminates.

This is also on Redhat using pdns-static-2.9.8-1.i386.rpm, which has no
debug data
so I cant get anything from addr2line.

However if I compile from 2.9.8 src (non static), i get
