hey,
i made some code to show information from the data units; some in the
c++ (ldu1.h, ldu1.cc, etc) and some in the python (traffic panel). now
when i leave it running for a somewhat extending period of time op25
dies with what i think is some sort of memory error:
*** glibc detected *** /usr/bin/python: free(): invalid pointer:

======= Memory map: ========
i omitted the huge memory map. i have no idea what to do with this sort
of back trace. any guidance will be much appreciated.
Cheers,
