Panic during backup

Hi Managers,

We have an environment of Alpha GS140 and ES40 running Tru64 Unix V5.1A
PK6. We have an EVA5000 and SAN. Backup is done using SAN-connected
library MSL6060 with Data Protector 5.1.
Recently, we faced some panics for different servers during the
scheduled night backups.
The following message found in messages file and binary.errlog file:
"panic (cpu 4): lw_remove: light weight wiring(s) found"
Also, a lot of CAM-SCSI errors noticed on the tape just before the
crash.
One of the servers was upgraded to V5.1B-3, and it faced the same
problem but with different message:
"panic (cpu 3): u_map_deallocate: u_map_delete failed while deallocating
map"

We tried to swap the library between different FC switches "edge switch
2/24" and different SFPs, but no change.

Both the crashed servers are running Oracle DB.

Could any one help us with the same if already faced similar problem?
Thanks.
