I did get this sequence of events on the last crash:
``` Sep 26 14:01:30 switch /sbin/kamailio[15614]: ERROR: <core> [receive.c:173]: receive_msg(): core parsing of SIP message failed (x.x.x.x:1111/1) Sep 26 14:01:33 switch /sbin/kamailio[15614]: ERROR: tm [t_reply.c:533]: _reply_light(): ERROR: _reply_light: can't generate 487 reply when a final 603 was sent out Sep 26 14:01:35 switch /sbin/kamailio[15613]: ALERT: <core> [main.c:740]: handle_sigs(): child process 15614 exited normally, status=255 ```
And that was a UDP receiver:
``` 15614 udp receiver child=0 sock=y.y.y.y:5060 ```
