nothing wrong with diffing the changes and see if theres a clue, but
to solve this one really needs to find the underlying cause no matter
what. changes can just hide bugs or make them more or less likely to
appear. can anyone provide at least a stacktrace or process snapshot
of the crashed dns processes? from that you try to build a theory of
what might be going wrong by thinking really really hard... (the
thinking should be directly proportional to the time it takes to
reproduce the bug) and then you work on how to prove that theory.
just changing stuff without knowing what exactly was the problem with
the old code is sometimes tempting, but wrong and dangerous.
