Right, currently the SCTP channels do no support SO_REUSEADDR. Though, I 
don't see any reason why they could not. That said, there appears to be 
a more specific SCTP option for this, SCTP_REUSE_PORT.

Is this something that would benefit you, if it were added?

This is very strange, can you get the output of netstat when in this state?
