I am wondering if any one seen this specific issue or anything similar ?
This error shows up in backup execs log only when trying to backup a
remote Netware OES server ( oes SP2 i.e. 6.5SP5 plus TSAUP19, plus other
post SP5 patches.)
Using the newest build of BEXEC.

Backup of the local filesystem on the media server is error free.
Remote backup produces the issue.
Backup to disk folder on the media server produces the same error.
Media server hardware is HP Proliant DL 360 G4 with disk and tape
subsystems on different controllers.
tape drive is (LTO3) HP Ultrium 960 in an HP storageworks 1/8 Autoloader
Remote server is same hardware platform disk controller and disk drive
I also have a second site with the same hardware and the same issue.
