Please check the status of the communication system at
a terminal, and carry out a restart if necessary.

all defined communication channels to the subystem are occupied
by other applications. Please deactivate any connections which
are not needed, and try again to set up a connection. Ask the person
responsible for the system to define additional channels if they are
a permanent requirement.
