APAR status
Closed as program error.
Error description
The symptom is a client using SCTP may attempt to fail over to the local server when the remote server goes down. This is due to the INITACK message claiming that the local host can be used which is done by adding 127.0.0.1 to the list of addresses in the INITACK message. The detailed symptom is to capture the INITACK message from the server and examine it. It will have the local host in it when it should not.
Local fix
Problem summary
SCTP connection from a remote host will fail, when there is already one sctp connection exists(server/client on the same host) in the local host.
Problem conclusion
If the connection is between local and remote host, then remove loop-back address from INIT and INIT-ACK packets. This will make sure destination does not try to reach the source through loop-back address.
