IJ50374: LOGASSERTFAILED: OWNED_BY_CALLER(LOCKWORDCOPY, LOCKWORDCOPY) WITH POLICY FILE MUTEX

APAR status

• Closed as program error.

Error description

• With File Audit Logging (FAL) enabled, when deciding to run LWE
  garbage collector for FAL, an attempt to try-acquire the lock on
  the policy file mutex is performed. If the policy file mutex is
  busy, the attempt is canceled and retry on the next attempt.
  Upon canceling, the policy file mutex can be released without
  being held leading to the log assert.  
  

Local fix

• - Disable FAL if it is enabled
