Error description

  • When dumping an IBM Rational ClearCase Versioned Object Base
    (VOB) database as part of:
    1) ClearCase MultiSite replica creation;
    2) moving the VOB to host running a different processor
    architecture;
    3) a maintenance operation;
    the dumper may fail with an out of memory error.
    
    At this time, the issue appears to be related to large directory
    checkin comments and a cache management issue in ClearCase.
    During the database dump operation, the dumper may use
    inordinate amounts of virtual memory, eventually exceeding the
    4GB allowed for 32-bit user processes.
    
    This issue is extremely rare, and the only known workaround is
    to perform the dump on a ClearCase 7.0.1.x host as the out of
    memory issue does not occur on ClearCase 7.0.1.1-IFIX01.
