Thread:Project:Support desk/Watchlist pages limit/reply

Not that I knew of. Maybe a theoretical one coming from the number of rows MySQL can handle inside a table... However, I have never heard of anyone actually really hitting on such a limit. In contrast I remember some months ago there was a bot, who had a programming mistake, which led to this bot watching every page, which it had edited. At that time that were maybe 1,2 million pages. It made the watchlist unusable (because it was filled with useless content), but it did not hit a limit.
