Private strand flush not complete
A "strand" is new terminology for 10g and it deals with latches for redo .
There is always shared strands and a number of private strands .
Similary the undo can be generated as 'in memory undo' and applied in bulk.
This affect the memory used for redo management and the possibility to flush it in pieces.
The message you get is related to internal Cache Redo File management.
You can disregard these messages as normal messages.
This issue is infact not a bug and is expected behavior.
In some cases, this message can be resolved by increasing db_writer_process value.
