How to use SO_LINGER to make SCTP connections end sooner after close?

Issue

  • How to use SO_LINGER to make SCTP connections end sooner after close?
  • We have a SCTP application which sends data and closes a socket, but the other end never replies. This results in the socket staying in CLOSED state or similar a long time, and applications cannot use the socket again, getting EADDRINUSE or "Address already in use". How can we avoid this?

Environment

  • Red Hat Enterprise Linux
  • SCTP (Streaming Control Transmission Protocol)
