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

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of backup command on t1 channel at 10/22/2007 09:11:50
RMAN-10038: database session for channel t1 terminated unexpectedly

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.

Stack trace from the trace file shows

Backup of the same archivelog files to disk, without using the MML, is successful.
