I'm running HEAD version from Jan 22 on an Alix board with an AMD Geode LX
processor (i386).  I can sustain 30 concurrent calls averaging around 70%
CPU utilization by the freeswitch process, measured by top.  Bypass media
and proxy media are disabled.  PCMU is forced on both endpoints (no

The problem is the RAM usage over time.  The board has 256M.  Idle,
freeswitch occupies around 4% after a fresh restart.  A minute or so after
30 calls are nailed up the RAM usage is about 7.2%.  After 5 minutes,
13.6%.  After 60 minutes, near 65%.  Disconnecting the calls returns the
RAM usage to 6-8%.

I've not tried to troubleshoot an issue like this before.  Is valgrind the
next step, or would something else make more sense?
