[OpenSER-Devel] RFC: memory management in database modules

[Bogdan-Andrei Iancu]

Hi Dan,

I agree - but on the other hand, if possible, we should try to reduce as 
much as possible the impact. If I'm walking on a muddy street, I try to 
get dirty as less as possible, even is 100% that I will get dirty in 
some percentage ;)

With the memory defragmentation is a different thing that might be also 
discussed, but in a separate thread.

Regards,
Bogdan
