I have found some looks very like the problem in crossbridge on github

crossbridge/javanet.c at f8c6eff42a2936d66c5a7aa1d5fbc35379985fb5 · adobe-flash/crossbridge · GitHub

_javanet_close:

while(error == TARGET_NATIVE_ERROR_INTERRUPT_FUNCTION_CALL);

I found this conversion:

TARGET_NATIVE_ERROR_INTERRUPT_FUNCTION_CALL == EINTR

and

crossbridge/uthread_recvfrom.c at f8c6eff42a2936d66c5a7aa1d5fbc35379985fb5 · adobe-flash/crossbridge · GitHub

errno = EINTR in _recvfrom

crossbridge/javanet.c at f8c6eff42a2936d66c5a7aa1d5fbc35379985fb5 · adobe-flash/crossbridge · GitHub

TARGET_NATIVE_NETWORK_SOCKET_SET_OPTION_SO_TIMEOUT (fd, optval, result);

here just setup timeout for recvfrom

If the value are match, the case I describe must happen if these code are relevant.
