This brings up another question:What if [EXCLUSIVELOCK] locks some db's, but fails to unlock them for some reason? Wouldn't that prevent all other requests to the same db's from executing until webcatalog is shut down and restarted?If so, is there some kind of timeout available to force the [EXCLUSIVELOCK] to end, so this will never happen? ================================ Kenneth Grome, WebDNA Consultant 808-737-6499 http://webdna.net ================================############################################################# This message is sent to you because you are subscribed to the mailing list
