[OpenSER-Devel] Memory Leak?

[Dan Pascu]

It's more likely that this is not a memory leak, but a memory 
fragmentation issue. If you happen to run a fifo command like ul_dump 
with a lot of active contacts, it'll allocate a lot of small fragments 
and the memory gets fragmented. Later even after the memory is freed, it 
will not be able to allocate a 500+ byte memory block because the memory 
is too fragmented and memory allocation will fail even when 90% of the 
pkg_memory is free.
