Hi

Netbackup 4.5, MP3 on W2K. 3 x SSO LTO drives. 3 x media servers connected to 
these drives. SIZE_DATA_BUFFERS = 65536, NUMBER_DATA_BUFFERS = 64 on all three 
media servers. 
Backups run fine on two of the servers, but we get intermitted error 84's on 
the third server. A backup will fail on this server with error 84, but run fine 
on the same server, a little later. Same tape used.
Can not be the drives, as the other servers use the same drives without any 
errors. Just error 84 on this server.

Any ideas where we can start to troubleshoot. 

We replaced the fiber cable without any change. Qligic 23xx HBA's.
