Hello
We are having some problems with TOSSIM segfaulting when we are running
longer
simulations.
We are trying to let a node sleep for a large amount of time (1346153000'ish
milliseconds).
To do this we first call SplitControl.stop() on the radio (ActiveMessageC)
and
then start a TimerMilliC for this period of time. After the timer is started
nothing else happens in the program as we wait for the timer to fire.
But before we apparently get the fired event, the program segfaults with the
trace below. The simulation runs for quite some time after starting the
timer, with nothing apparently
happening until this happens though.
We are using the meyer-heavy.txt noise readings, and are running an
unbounded number of events.
Does anyone know what might be going on? ANY help is appreciated!
Program received signal SIGSEGV, Segmentation fault.
