[Veritas-bu] Intermittent ORA-19511 with Oracle RMAN

A little environmental info:

client:

RedHat Linux ES 4
Net Backup 5.1 MP5
Oracle 9.2.0.6

Master and Media Server:

Windows 2003 Server SP1
NetBackup 6.0 MP7

Intermittently I am seeing the following errors on 2 nearly identical linux servers
when backing up some Oracle databases.

channel ORA_SBT_TAPE_1: starting piece 1 at 11-FEB-09
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of backup command on ORA_SBT_TAPE_1 channel at 02/11/2009 05:17:57
ORA-19506: failed to create sequential file, name="PROD_T20090211_db_s6095_p1_t678518252", parms=""
ORA-27028: skgfqcre: sbtbackup returned error
ORA-19511: Error received from media manager layer, error text:
VxBSACreateObject: Failed with error:
Server Status: socket open failed

I've searched the Veritas support site and googled for this, without finding anything useful.

There are some recommendations from veritas to check name resolution.

This error occurred on one server this morning.

The time previous to that was two weeks ago.

Any ideas on what this may be?
