    * USERS AFFECTED:                                              *
    * Users running software builds in ClearCase dynamic views on  *
    * Linux systems, with ClearCase version 8.0.0.6 or higher, or  *
    * 8.0.1 or higher.                                             *
    ****************************************************************
    * PROBLEM DESCRIPTION:                                         *
    * A change made in a previous fixpack modified the locking     *
    * algorithm in some build auditing functions.  On some Linux   *
    * systems, there was unanticipated processing overhead         *
    * introduced by those changes.                                 *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    

Problem conclusion

  • The previous code changes were modified to eliminate the added
    overhead on Linux systems.
