Call the client IP's EP1 and EP2, and the server IP's EP3, EP4. Assume EP1
and EP3 make up your successfully-heartbeating, active path. Do you _have_
working routing between the other EP's (check with ping -I <EP2-interface>
<EP4-address> etc.)

Best way to debug these is to start from the ground up - ensure the IP layer
is functioning as expected first, if you have not already done so. It seems
from your description that neither end is even trying to heartbeat the
'other' remote end-points - which is often points to a misconfiguration of
the routing table.
If that's not the case - turn on the sctp debugging - and send the output of
/proc/net/sctp/* so we can see what state the kernel thinks the associations
are in.
