But that is the point, you can't. You constantly allocate memory for 
processing SIP messages that vary in size, plus small chunks allocated 
for parsing certain headers that also vary a lot in size. It doesn't 
matter much if memory gets fragmented after 3 days of usage or after 6.

There are about 700 places pkg_malloc is used in the code and about half 
of that where shm_malloc is used. Relying on programming guidelines to 
avoid fragmentation will simply not work.

If you keep walking long enough you'll keep getting dirtier. I expect my 
proxy to run for a long time without restarts.
