Unless it's a problem with the network connection it's probably a
problem with the number of connections allowed by the MySQL server.
This is usually set up to 100 by default, it should be increased to
something like 500.
MySQL has admin tools to monitor the connections to the server, use it
to monitor the number of connections and what's causing it.
