At first I was assuming that it was because of archiving, but the OP says that's turned off. Unless it had been on and there wasn't a *restart* after changing the configuration, I can't see how this could happen, and was hoping someone else could cast some light on the issue. The one setting that gave me pause was: commit_siblings=200 but it doesn't seem like that should matter with: commit_delay=0; -Kevin
