If the db, user, etc. tables in the mysql system database (containing
privileges, etc.) contain host names instead of IP-addresses I suspect
it needs a DNS to resolve these...

MySQL server was probably waiting for a bunch of DNS requests? Until a
timeout occurs it will probably keep the connection waiting. This can
cause a lot of connections to occur until you reach max_connections at
which point it will not accept new connections anymore.
