At least, that's how I read sleepcat's description: 5. Fix a bug where cache buffer retrieval could race with a checkpoint call, potentially causing database environment recovery to fail. [#14657] Given that OpenLDAP checkpoints on shutdown, shutting down the server could be what is triggering the issue for you. I'd suggest applying the patch and seeing if this resolves your problem. Yeah, the patch may not apply for you (I have a 3.5GB cache, so it does for me). Wouldn't harm anything, of course, if you decided later you needed a larger BDB cache. ;) --Quanah -- Quanah Gibson-Mount Principal Software Engineer Zimbra, Inc -------------------- Zimbra :: the leader in open source messaging and collaboration
