[Discuss-gnuradio] RAM consumption

[David Knox]

I am running some Zigbee code from UCLA with some modifications of my own...
When I run the (modified) code, RAM is slowly (but surely) consumed with
high CPU usage.  After about half an hour, the CPU/RAM monitor shows 100%
RAM usage and then operation stalls and CPU usage drops down once again to
quiescent levels, with RAM remaining tied up until the program is ended
(ctrl-C).  Until the stall, program operation appears to be correct.

I have reviewed the code by hand for memory leaks and also used some of the
tools available for detecting memory leaks without any results.  Has anyone
else had similar problems and, if so, how did they debug them?  Is this kind
of inexorable creep of system memory usage symptomatic of anything else? 
Within GnuRadio, is there any method for quickly determining how program
memory (heap space) or data memory is being consumed?
