During an outage, the Standby Database took over the Primary Role.
Backup of the archivelog files from the new Primary database fails with

Alert.log shows the corresponding error is an
ORA-07445: exception encountered: core dump [__GI_strlen()+64] [SIGSEGV] [Address not mapped to object] [0x000000000] [] []

Commvault Galaxy 6.1.0 (Build50) is the MML being used to back up to tape.
