Image cleanup error 174

Hello,

I'm getting an error 174 on our image cleanup jobs. All Full backups are writen to disk and tape. Incremental backups are written only to disk.

 

Master server  Solaris 10 running NetBackup 7.5.0.7 (SolMasterSvr)
Media server Winfows 2008 R2 running NetBackup 7.5.0.7 (WinMediaSvr)
Client server SLES 11 SP2 VM , VMware backup (SuseClientSvr)

Job Details
Cridital bpdm (pid=4016) Storage Server Error: (Storage server: PureDisk:WinMediaSvr) MBPOAddList Failed to complete PO addlist webservice ((unknown)) V-454-36

granted resourse MediaID=@aaaaY,PureDiskVolume;DiskPool=Dedupe_WinMediaSvr_DP;Path=PureDiskVolume;StorageServer=WinMediaSvr;MediaServer=WinMediaSvr manager - system error occurred (174)

The 1st 3 lines repeat several times before we get the final error (last 3 lines).

The policy that runs the the job for SuseClientSvr gets error of 84, when run. All the other servers in this policy are backing up just fine.

Can someone piont me in the right direction.
