[Pdns-dev] memory leak

Hi Bert

I'm trying to hunt down a nasty memory leak - with little success up 
to now. Each time an exception is thrown from a backend and the 
backend is recreated by the guardian, 2048 bytes are added to the 
memory used by the instances.

First I thought the factory classes are instanciated but the old 
instance is not deleted. But this doesn't reduce the memory leak, so 
I'm a little bit desperated because the code is a little bit complex 
(or to be more precise: interweaved). Could you please give me some 
hints, what is going on if a backend is recreated (and which files I 
have to look into other than dnsbackend and ueberbackend).


Norbert

PS: Additionally I've found a small memory leak in the bindbackend 
constructor. Patch attached.
