I did have a connection prior to the binding. If I can reproduce I will test against the 4.8.x kernel when I am able. This is a live system and requires coordinate with others.

Any suggestions on how I can tell what is holding the ports open, or how to reset the sctp port table in the kernel? > > Lksctp-tools verison: 1.0.16 > Kernel version: 4.4.6 Did you have sctp connection and sctp traffic before this binding ? It maybe an asoc leak in 4.4.y kernel. If it's reproducable, can you try against this commit(or with 4.8.y kernel) commit b61c654f9b3f1a271217e46c893f80565b1f754d Author: Xin Long <lucien.xin@xxxxxxxxx> Date: Wed Sep 14 02:04:20 2016 +0800 sctp: free msg->chunks when sctp_primitive_SEND return err > IP-Family: IPv4 > Number of addresses passed to sctp_bindx(): normally 2, have tested > with each address individually > > frm > > > Franklin Marmon > The Hyde Company > 331 East Broadway > Missoula, MT 59801 > > Office: 406.541.4777 > Cell: 406.493.2460 > http://www.hydeco.com > marmon@xxxxxxxxxx > > > -- > 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 -- 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
