Abort chunk in SCTP

Question

I am using LKSCTP in my project, one sometime I see that by box receives About chunk from the peer. Now question is what are the possibilities for which we can receive abort chunk from remote.

Answer 1

Many reason, more than would be efficient to name in a single email. The abort chunk however should have a string encoded into it giving some explination for the abort. User space apps IIRC can read that string (or you can look at it in a tcpdump if you need to). That will give you some clues regarding the root cause.
