bpsink core dumps when fails to bind #46

dklimkin · 2023-07-14T14:41:45Z

In case the bind port is already used, boost::system::system_error is thrown which leads to terminate and a coredump:

[ bpsink   ][ info ]: This is HDTN version 1.0.0
[ bpsink   ][ info ]: starting..
[ bpsink   ][ info ]: All LTP UDP engines can receive a maximum of 65535 bytes per packet
terminate called after throwing an instance of 'boost::wrapexcept<boost::system::system_error>'
what():  bind: Address already in use
Aborted (core dumped)

This should probably be handled nicer.
