I would also turn on mysql's slow-query log to see if there are any crazy
queries going on. In fact, log all queries. The fact that the original
problem involved database connection issues hints at a mysql angle. A few
bad queries can tank a server.

4,000 pages a day, is just not that much.
Then also look at server memory usage.
