As a side note to the discussed issue, I don't think it is realistic to 
assume that memory fragmentation will not occur by just avoiding some DB 
memory allocations that vary in size too much. Given the varying size of 
SIP requests, over time, if the proxy is online for a long time and 
servicing many requests per second, memory fragmentation will occur 
sooner or later, unless the memory allocator is smart and works around 
it, or if it has a defragmentor that is run when memory gets too fragmented.
