Scope
per-process

This option controls whether or not clusters support the hot/seamless restart of applications. Enabling this reuses existing stacks in the cluster to allow up to two processes per stack to bind to the same port simultaneously.

Note: It is required there will be as many new sockets on the port as old ones; traffic will be lost otherwise when the old sockets close.
  • 0 - disable per-port stack sharing (default)
  • 1 - enable per-port stack sharing for hot restarts.
