Abstract

PI89036 causes native_stdout to fill up with repeating debug timestamps

Download Description

PH24552 resolves the following problem:

ERROR DESCRIPTION:
WAS ND 9.0.5.3 and 8.5.5.17 on Windows

After updating to WAS 9.0.5.3 or 8.5.5.17, PI89036 results in continual
debug timestamps generated to native_stdout:

ProcessCPU
Java_com_ibm_ws_xd_pmi_processcpu_ProcessCPU_nativeEnableDebugMode ENTER
ProcessCPU
Java_com_ibm_ws_xd_pmi_processcpu_ProcessCPU_nativeEnableDebugMode 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]
...

LOCAL FIX:
none

PROBLEM SUMMARY:

USERS AFFECTED:
All users of IBM WebSphere Application Server

PROBLEM DESCRIPTION:
native_stdout.log on Windows fills up with repeating debug timestamps when
PMI is invoked to collect CPU statistics

RECOMMENDATION:
None

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 out
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
