I think I find out what happen.

Killall function terminate all running processes but doesn't clear the event
queue or something like it. At the time the event( or some requests) are
handled by SIMIX it want to access the data which are within the processes
and then the program exit with segmentation fault.

Anyway, I solved that by putting off the killall function.
