Just spitballing here... you were running the removal of the oldest in the background while bringing in new data for the backup. Maybe it was hitting an I/O ceiling of some kind under those conditions? May still warrant investigation since it could still hit this "ceiling" under a big enough I/O load. -- Aaron Mason - Programmer, open source addict I've taken my software vows - for beta or for worse
