This situation usually shows up after a migration, but could be found at any time you have been working with resources. QCONSOLE still remains in QCTL when you would have expected it to be reassigned as another workstation.
Be sure that the system has not been IPLed with DEBUG turned on. A good indication is that no other interactive subsystem has started, if present, and others may also be absent. Check SYSVAL QIPLTYPE it should be 0.
