Opened: Oct 22, 2019

Severity: 3-Major


When an outgoing SCTP connection is created using an ephemeral port, the connection may appear to be open after an SCTP connection halt. This prevents new connections to the same endpoint, as the connection appears to already exist.


New connections are unable to be created resulting in dropped messages.


-- A virtual server configured with an SCTP profile. -- An outgoing SCTP connection after an existing connection to the same endpoint has halted.



Fix Information

SCTP connections can now be halted and recreated to the same endpoint.
