Summary:                    Memory leak in iax2-parser.c
Description: 
We have found compiling asterisk without LOW_MEMORY has a memory leak in
iax_frame_new. It seems that the AST_LIST_TRAVERSE_SAFE_BEGIN macro is not
traversing the linked list in good way.
We have traced adding some ast_log in the code that iax_frame_free add
buffers in the frame cache linked list and after that iax_frame_new does
not find this free buffer in the list and allocates a new buffer with
ast_calloc_cache.
With the time and with our system, that receives too many calls, asterisk
gets all the available memory in the system and produces an error.
If we compile with LOW_MEMORY, then this piece of code is not compiled and
asterisk does not have memory leaks.

I have uploaded a patch that will add some additional debug information. 
Please apply this and let me know what the text is of the ERROR log
messages that show up.  It will print out the name of the thread that has a
full frame cache.
