Hi All,

The situation is getting crazy. Last night 17% of our backups failed with error code 47. It happened on only 6 of the 58 media servers. All the jobs were trying to backup up to one of two of the four VTL libraries. Looking at the <16> and <32> errors in /usr/openv/netbackup/logs I see CORBA errors on 3 of the six and Robot Failures on the other three. While we have many 47 errors on the weekends, this is a first of this magnitude for a week day. The only change I am aware of is: last week we increased the memory of 5 of the 6 media servers from 12GB to 32GB. Is it possible to have TOO much memory?

Environment:

RedHat Linux 64bit running 32Bit NetBackup 6.5.6

4 EMC VTL Libraries (sorry don’t know model #) 164 drives configured on each.

The failing clients are both UNIX and Windoze with one Oracle backup failure.

OH, and they only seem to happen between 23:00 and 04:00 (approximately)

ANY suggestions would be greatly appreciated.

Regards,
