---------------------------------------------------------------------- 
As you can see from the output, these are all the frame caches managed by
ast_frdup() so that it can reduce memory allocation/freeing (thrashing). If
you don't want frame caches to be used, build Asterisk with LOW_MEMORY
defined.
