"ORA-00270: error creating archive log" on Standby Database

We have been receiving the below error on our standby database continuously since last 4-5 days.

*ORA-00270: error creating archive log ORA-17611: ksfd: file '31' cannot be accessed, global open closed*

There is no FRA space issue on Primary as well as Standby Database. No abnormal shutdown on Standby Instance. Redo logs are still being applied on Standby.

Please let me know if anyone has faced similar issue or have come across solution. We have raised SR with Oracle on same, but have not progressed much.

DB Version: EE 11.2.0.3.0 - 64bit Production on AIX

Thanks!
