So, on this line socket state (SST) is 7 which is SCTP_SS_CLOSED. This means that you performed a close() call. The association state (ST) is 4 which is SHUTDOWN_PENDING. This means that when you tried to close the socket, the association thought that there was some pending data. I seem to remember you and I discussing this situation before, but I can't find that thread. I'll take another look at how PR interacts with queue state to see if we can detect the proper empty state to send a SHUTDOWN. However, what the above tells me is that you don't actually set SO_LINGER on this socket. If you did, instead of attempting SHUTDOWN, we would have sent an abort. That might be a good workaround until we solve this "queue empty" problem.
I will give this a try when i get to the office. I am certain we linger on the server. On client side, at one point we turned off heartbeats on the client side and that typically goes with linger on. I will double check. cheers, jamal -- To unsubscribe from this list: send the line "unsubscribe linux-sctp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
