texte = We did. This might happens if Windows locks a file that WebDNA is trying = to write to, or if there are multiple instances of WebDNA running and = trying to write to a single database. I do not think the multiple = instance case is the problem here. WebDNA spits out an error first = before deadlocking. This is why i think we need to know why Windows = would lock a WebDNA database, and why this happens suddenly (and = regularely) after years of error-free service. If this comes from = WebDNA, a reinstall would solve the problem. In this case, i believe = Windows (an update, a specific module or extension) is to blame. - chris On Jul 10, 2011, at 19:52, Stuart Tremain wrote: > Very strange that this problem is happening to another Windows Server = user.
