What FreeBSD version are you running on both sides? Is it 10,3R as reported= in the bug? Do you mind trying -head to rule out any fixes? Server sends FIN and on the following request sends RST which gets dropped somehow and doesn't reach client. But even after receiving first FIN, client asks for data to which servers reopens the connection (which seems like the real bug), sends data and again sends FIN after that. Now client acks that = FIN and sends its own FIN which server acks but client now doesn't like it. So = it keeps sending FIN which server keeps acking. Also, client and server seem off by 10seconds? --=20 You are receiving this mail because: You are the assignee for the bug.=
