Error description

  • IBM Rational ClearCase builds intermittently hang and D-state

    dentry.

Problem conclusion

  • The ClearCase MVFS filesystem was changed to detect and prevent
    an error condition which caused the occurrence of D-state
    processes.  This is fixed in ClearCase versions 8.0.1.15,
    9.0.0.5, and 9.0.1.1.
