Richard Mudgett commented on ASTERISK-27447:
--------------------------------------------

Today's backtrace files have no symbols and are useless.  Please do not include core files unless specifically asked.  Core files are large and for the most part only usable by the machine that generated them.

No.  I don't know of any problems disabling cache_media_frames.  Caches simply trade memory for speed.  cache_media_frames=no was specifically created to allow valgrind or MALLOC_DEBUG to track media frame buffer use better.  Since the MOH crash you experience seems to be related to media frame buffer use, you need to set cache_media_frames=no when running with MALLOC_DEBUG.
