Errorin POA logs

I'm running GroupWise 8.0.3 on Linux. I was checking my POA log files recently and saw the following errors during the quick indexing.

08:00:30 F22F The database function 29 reported error [C05D] on dmdd0701.db
08:00:30 F22F The database function 87 reported error [C05D] on dmdd0801.db

08:00:30 F22F The database function 29 reported error [C05D] on dmdd0901.db
08:00:32 F22F The database function 87 reported error [C05D] on dmdd0001.db
08:00:32 F22F The database function 87 reported error [C05D] on dmdd0001.db

I know it is trying to index document management DBs but can't find anything on the errors or how to fix them. Any insight would be great.

Thanks
