Summary:                    Memory Leakage
Description: 
Asterisk trunk version (157167) seems to have a major memory leak. The
memory leak increases with evey call and never reclaims.

This is not the proper way to see if memory is leaking.  Modern OSes will
always use memory if it is available.  The number that ps is giving back to
you is useless.  If you suspect a memory leak, compile asterisk with
MALLOC_DEBUG and use the 'memory show summary' and 'memory show
allocations' commands to print out how much memory asterisk is actually
using (as opposed to what is being cached in memory by the OS).  I am
closing for now, since this is most likely not a bug.  If you find some
real numbers through MALLOC_DEBUG, feel free to reopen this issue and post
your findings.
