Hi Yuriy,
the crashing line is almost unchanged from the code you submitted in
2009. Its crashing in the strcmp() that compares the media IP to the
fromIP. Since the fromIP looks ok fine your core dump, maybe the media
IP gets changed that instant and we need a lock to fix that race
condition ?
Regards,
Jan
