Which client did yo use? We just released 1.4 that solves a TON of problems. Would like to hear about your problems being solved an especially those still persisting.

Again, try the new version 1.4. As discussed in https://github.com/owncloud/mirall/issues/29 inotify on linux does not guarantee that the sync client will get notified of file changes under all circumstances, so we do need to poll. Any constructive hints are welcome.
