APAR status

  • Closed as program error.

Error description

  • When building using heavily parallel audited builds in an IBM
    Rational ClearCase dynamic view, a resource deadlock
    may occur under heavy load that may cause builds to stall.
    
    This issue appears most often in ClearCase 8.0.0.6 and later and
    has only been reported on several platforms.
    

Local fix

  • Currently the known workarounds are:
    - Periodically reboot the build hosts. This seems to keep the
    problem in remission
    - Back down to ClearCase 8.0.0.5. This backs out of an MVFS
    change that may be related to this issue.
