First, your posts show no evidences of the CS storm bug. Second, 300 *new* connections a second is a lot. Each new connection requires a significant amount of both database and OS overhead. This is why all the other web developers use a connection pool. In fact, I wouldn't be surprised if your lockups are on the OS level, even; I don't recall that you cited what OS you're using, but I can imagine locking up Linux 2.4 trying to spawn 300 new processes a second. --Josh
