a debugger process from a previous debugging session has been
 terminated

    Facility: DEBUG, VMS Debugger

    Explanation: While attempting to create a process to run the
    debugger, a debug process from a previous debugging session was
    found and terminated.

    User Action: Under normal circumstances, the debugger process
    will exit when a debugging session ends via the EXIT or QUIT
    commands. If the previous debugging session was terminated with
    an EXIT or QUIT command and this error is reproducable, then
    submit a Software Performance Report (SPR)
