I have a backup job (for an NSS volume) which stops about half way through on an OES2SP1 linux cluster node (Hosted in VMWare ESX 3.5).
The Message log shows "OID_AddEntryIfNotThere - Unable to map GUID to DN using NCP eDir" repeating about 26 times per second for the duration of the backup.
Other nodes also show this error for the duration of their respective backups but all seem to complete successfully.
All nodes have eDirectory installed and hold replicas of their partition, and the backup software is HP DataProtector 6 with patches for NSS support.

Any ideas?
