Applies to:

Oracle Database - Enterprise Edition - Version 12.1.0.2 and later
Information in this document applies to any platform.

Symptoms

On database version 12.1.0.2, instances began crashing with ORA-600 [1433] and/or ORA-600 [ksasnd_rel_1] several minutes after Oracle ZFS Backup Appliance (ZBA) was shut down. The ZBA was only used for RMAN backups and after the ZBA was shut down all shares were unmounted.

Two types of database crashes were observed:

1) ORA-600 [1433] from various DBWn (database writer) and TTn (redo transport) processes. A stack from a DBWn process would be similar to:

[02]: ksaamb [VOS]<-- Signaling
[03]: ksasnd [VOS]
[04]: ksbasend_internal [background_proc]
[05]: kcbbdrv [CACHE_RCV]
[06]: ksbcti [background_proc]
[07]: ksbabs [background_proc]
[08]: ksbrdp [background_proc]
[09]: opirip [OPI]

 

2) ORA-600 [ksasnd_rel_1] from PMON processes with stack:

[02]: ksasnd_rel [VOS]<-- Signaling
[03]: ksbasend_internal [background_proc]
[04]: ksz_so_del [VOS]
[05]: kss_del_cb [VOS]
[06]: kssxdl [VOS]
[07]: kssdch_int [VOS]
[08]: ksz_cln_proc [VOS]
[09]: ksudlp [ksu]
[10]: kss_del_cb [VOS]
[11]: kssxdl [VOS]
[12]: ksuxdl [ksu]
[13]: ksuxda_del_proc [ksu]
[14]: ksucln_dpc_cleanup [ksu]
[15]: ksucln_dpc_dfs [ksu]
[16]: ksucln_dpc_main [ksu]
[17]: ksucln [ksu]
[18]: ksbrdp [background_proc]
