Thread:Project:Support desk/Won't Access Database: Too many open links/reply (4)

The default for max_conections was 100 and in current MySQL versions is 151. So only having 20 is ... kind of lame. Anyway, when you say that installation does not even work, then at that moment you are not using 20 connections, but you are trying to use exactly one connection and not more. I know of a wiki, which is used more or less frequently and there something like 25 connections is enough to serve all visitors. If you cannot even make one single connection to MySQL, then this effectively means that MySQL is not usable for you on this server. MediaWiki (and also many other nice systems) won't work without database access. If the host cannot fix his setup, then I would change to a host, where you actually can use what you paid for.
