Error description

  • Severity: 2
    Approver: BEH
    Compid:   5724K1000 Tivoli Universal Agent
    Abstract: UA on Windows: Script DataProvider may terminate O/S
    process
    
    Environment:
    This problem was reported for Universal Agent on Windows 2008
    
    Problem Description:
    UA SCRIPT Data Provider has logic to check for a whether a
    launched script process has not completed within its alloted
    time, 60 sec by default or per RUNTIME setting in metafile.
    Before UA terminates the script process it iterates thru any
    child processes spawned by the Script process.  Due to some
    unknown Microsoft defect in CreateToolHelp32Snapshot() API on
    very rare occasion the data returned indicates the O/S binary
    CSRSS.exe as being a child process of customer's Script
    processed, UA terminates this CSRRS.exe, as it does any child
    process, and then customer encounters BSOD.
    
    Detailed Recreation Procedure:
    Not recreateable; problem has occurred only in Windows 2008 at
    customer installation.
    
    Related Files and Output:
    This problem cannot be determined by trace log.
    

Local fix

  • This problem can occur when a launched script process has not
    completed within its alloted time, 60 sec by default or per
    RUNTIME setting in metafile.
    If you can guarantee the script finishes within its alloted
    time, this problem will not occur.
    

Problem summary

  • On Windows, the Universal Agent script data provider may
    terminate an unrelated process.
    
    
    This is a rare and random condition of the Universal Agent
    script data provider that has only been seen on Windows 2008 to
    date. In this case, the user's script was running frequently
    throughout the day, and the process CSRSS.EXE had been
    terminated only once during the year.
    

Problem conclusion

  • For reasons unknown, Microsoft's process API
    CreateToolhelp32Snapshot may return an incorrect parent process
    ID on a very rare occasion. Various forums on the Web indicate
    it is highly improbable that Microsoft will address this flaw.
    
    It is this incorrect parent process ID that causes Universal
    Agent to mistakenly terminate an unrelated process such as
    CSRSS.EXE. In this user's case, the process was related to
    critical OS processing, and the effect of terminating CSRSS.EXE
    crashed the Windows OS.
    
    This issue has been mitigated by providing additional process
    checks before a process is terminated.
    
    The fix for this APAR is contained in the following maintenance
    packages:
      | fix pack | 6.2.2-TIV-ITM-FP0009
      | fix pack | 6.2.3-TIV-ITM-FP0002
