All talk of SQLite and fsync is over my head, but FWIW, my server uses XFS and I've had no issues specifically with FF, other than that all clients get unresponsive/sluggish when somebody attempts to play a youtube video fullscreen, but that doesn't sound like what people are describing in this thread. My point being that the FF3 problems could well be an ext3-only issue, as Jordan sort-of implied. Or would other filesystems flush their cache in the same way? db ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _____________________________________________________________________ Ltsp-discuss mailing list.
