Error description

  • When performing highly parallel build processes in IBM Rational
    ClearCase dynamic views (> 400 simultaneous compile/link
    sessions) on a single ClearCase client, the MultiVersion
    FileSystem (MVFS) driver may encounter a fault condition and
    initiate a "Stop" event, also referred to as a "BSOD."
    
    Analysis of the dump files shows that the IRP stack is corrupted
    and is under investigation.
    
    This generally does not occur in less highly-loaded
    environments.
