Problem: the psid terminates after startup reporting that the port 886 is in use.

By default, the psid uses the port 886 (UDP) for the RDP protocol (inter-daemon communication). If this port is already in use, the daemon refuses to start-up and terminates immediately.

Make sure no other process uses this port. Or use the RDPPort directive within parastation.conf to re-define this port for all daemons within the cluster.

See also parastation.conf(5).
