ORA-00322: log 41 of thread 2 is not current copy

On a Data Guard Physical Standby, I noticed the following in the alert log:

Fri Jan 13 08:12:39 2017 
Errors in file /u01/app/oracle/diag/rdbms/v1s/V1S1/trace/V1S1_arc1_399861.trc: 
ORA-00322: log 41 of thread 2 is not current copy 
ORA-00312: online log 41 thread 2: '+RECOC1/V1S/ONLINELOG/group_41.3099.912775569' 
ORA-00322: log 41 of thread 2 is not current copy 
ORA-00312: online log 41 thread 2: '+DATAC1/V1S/ONLINELOG/group_41.807.912775567'

If you read metalink note:
Physical standby – alert*log shows ORA-322, ORA-312 intermittently (Doc ID 1592057.1)

SYMPTOMS

alert.log shows intermittently ORA-322 and ORA-312 for SRLs (standby redo logs).

CAUSE

These errors are written due to a very small timing window, when the SRL header
is being updated to reflect new content from the primary and in the same way
the ARCH process is doing its activity and seeing a CF flag entry that reflects an earlier
state.

SOLUTION

check the alert.log for any further issues. As long as ORA-322, ORA-312 is not combined with other issues, you can ignore this error.
