Hi

I suffered a case on a SCTP connection.

HOST A sends INIT chunk to HOST B
HOST B returns INIT_ACK chunk back to HOST A
HOST A sends COOKIE_ECHO chunk to HOST B
HOST B then send ABORT chunk with T-bit set to 1.

Any idea on why ABORT chunk is sent out?

Hi,

I have reports of this too, specially on load times, but the cause is
still an unknown..

Do you have a reliable, minimal reproducer?

Hello.

I do not know which version you use.
But I observe similar issue and in my case 
it was problem with sk_ack_backlog
sctp-Fix-sk_ack_backlog-wrap-around-problem.patch

With best regards Vasyl.

Is it an update of lksctp can help? or I should need to patch the kernel?

https://git.kernel.org/cgit/linux/kernel/git/davem/net-next.git/commit/net/sctp?idÓ217b15a19a4779c39b212358a5c71d725822ee

Afaik, that's part of RHEL7, so you might need to check if your kernel
already includes that. If so, then there's likely a different bug else
where. But as I asked already, do you have a reliable, stand-alone
reproducer for this issue?

Thanks,
Daniel
