Cut&paste error there. That second line should read "vm.dirty_bytes=134217728". The idea is to block the writer if the page cache gets sufficiently backed up. You can also try turning down vm.dirty_writeback_centisecs and dirty_expire_centisecs, within reason... That should also help to keep the writes flowing. Sorry this didn't help. Good luck. - Pat
