[erlang-questions] gen_sctp multi-homing

[Mikael Lixenstrand]

Still haven't figured out what the problem might be. I try another time here

I tried this in the erlang shell with a running program with
gen_sctp:open([{ip, {10,80,250,112}},{ip, {10,70,128,96}} ,{port,33333}] ++
?sctp_options),

{ok, Socket} = gen_sctp:open([{ip, {10,30,40,50}}]).
{ok, Assoc1} =gen_sctp:connect(Socket,{10,80,250,112},33333,[], 6000).
{ok,{sctp_assoc_change,comm_up,0,10,10,1}}

{ok, Asso21} = gen_sctp:connect(Socket,{10,70,128,96},33333,[], 6000).

=ERROR REPORT==== 2-Jun-2008::08:52:19 ===
Error in process <0.38.0> on node 'asd@REDACTED' with exit value:
{{badmatch,{error,eisconn}},[{erl_eval,expr,3}]}

** exited: {{badmatch,{error,eisconn}},[{erl_eval,expr,3}]} **

Someone have any idea what the problem might be?
I'm using R11B-5.
