At least not in the activity monitor. You can see a status 85 in the bptm log from the media server. This is occurring for more than one tape as you can see below so I'm guessing this is not bad media. I thought it most likely a SIZE_DATA_BUFFER issue. I'm still digging but this is what I have so far. Any help is appreciated.
Master and all media servers are AIX. This has been attempted on both the media server that ran the backup job and alternate media servers.
The following are from the bptm log on the media server:
