Hi Clifton ,
Are there any further clues in the trans.log file ?
If possible can you paste it here ?
The error could also possibly be because of insufficient authorizations for OPS$ users.
Are there any other problems within the system like backup failures which may suggest this ?
Just in case, Check this note
