    ****************************************************************
    In a very specific scenario, multiple requests to db_server
    process will make lockmgr keeping incorrect signal handler
    for SIGALRM. Then db_server will core dump after receiving
    SIGALRM.
    

Problem conclusion

  • A fix is available in ClearCase versions 7.1.2.8 and 8.0.0.4
    

Temporary fix
