Error description

  • WAS ND 9.0.5.3 on Windows
    
    After updating to WAS 9.0.5.3, PI89036 results in continual
    debug timestamps generated to native_stdout:
    
    ProcessCPU
    Java_com_ibm_ws_xd_pmi_processcpu_ProcessCPU_nativeEnableDebugMo
    de ENTER
    ProcessCPU
    Java_com_ibm_ws_xd_pmi_processcpu_ProcessCPU_nativeEnableDebugMo
    de EXIT
    
    followed by a series of timestamps every 15 seconds:
    
    [04/16/20  14:39:06]
    [04/16/20  14:39:06]
    ...
    [04/16/20  14:39:21]
    [04/16/20  14:39:21]
    ...

    ****************************************************************
    Over a period of time, native_stdout.log on Windows fills up
    with
    repeating debug timestamps when PMI is invoked to collect CPU
    statistics. This was caused due to a fix for PI89036 which
    failed
    to check for debug mode prior to writing out some timestamps in
    the
    log file.
    

Problem conclusion

  • The code was updated to check for debug mode prior to writing ou
    timestamps to native_stdout.log.
    
    The fix for this APAR is targeted for inclusion in fix packs
    8.5.5.18 and 9.0.5.4. For more information, see 'Recommended
    Updates for WebSphere Application Server':
