sample program echo_server response abort message #670
Comments
Do you have sctp compiled into your kernel?
User SCTP is in user space, and if the kernel has a SCTP stack in it, your user
space stack, which is listening will not get the packets and instead the kernel will..
And of course it will respond with an ABORT.
You should validate your kernel configuration does *not* include SCTP
