Error description

  • When performing distributed builds using IBM Rational ClearCase
    clearmake, the Automated Build Executor (abe) processes may
    crash when idle under the following conditions:
    1) The abe is idle
    2) the parent clearmake process is monitoring one or more other
    abes that are running time-consuming build processes
    3) the idle abe times out (3 hours by default, or as per the
    CCASE_ABE_TIMEOUT environment variable).
    
    When this occurs, the abe process may crash and generate a core
    dump. This error may be seen in the clearmake output:
    
    clearmake: Error: Error decoding record type from stream.
    clearmake: Warning: Abe abe(1, pid=8546, 'builder1') will be
    shut down.
    
    or this error may be seen at the end of the build:
    
    ??? 10:25:52.36024897188659387 (clearmake):
    bldsvc_shutdown_abe_channel: abe already closed.
