Problem conclusion

  • This problem is fixed in 5.2.1.1
To see all Spectrum Scale APARs and their respectiv
Fix solutions refer to page: 
https://public.dhe.ibm.com/storage/spectrumscale/spectrum_scale
_apars.html


Benefits of the solution:
Avoid logAsserts on file audit logging code when file audit
logging is enabled

Work Around:
Disable file audit logging

Problem trigger:
The problem happens when the file audit logging code is writing
to the audit log, and attempts to grab a lock on the file. This
happens frequently in file audit logging code, but the condition

does not happen every time, so the logAsserts will be periodic.

Symptom:
Abend/Crash

Platforms affected:
Linux Only

Functional Area affected:
File Audit Logging

Customer Impact:
High Importance
