There were lot of delete/update/insert at that time on your database and your archiving was too much at that time... also try to use separate disk/mount time for your arch destination to avoid write contention at that time....

After a few seconds ARC0 successfully archives 51809. Similarly rest of the seq# get archived to after a few tries by one archiver or the other. This behavior is not regular, it appears off and on, most of the times there is no failing, and everything proceeds normally. I was wondering if any of you can explain the following points to help improve my concepts, * Is FAILING temporarily any threat? * What could be the reason for it? * If the first archiver fails (ARC0) and then the second (ARC4) fails too, why does it try to archive the next seq# rather than finishing the previous one? * Any reason for this inconsistency?
