That is what I think too. I see, on average, about 30-40 connections in MySQL using its "Workbench" tool. And that looks fine, that corresponds to the way I configured the pool. But I must say that I hadn't always used the pool. In the past I used to use just one connection, and in many methods I had forgot to close the resultset. You can imagine how much my app crashed! I couldn't even sleep at night! Then I fixed my app so it closes every result set it created, then the statement, and then "close" the connection so it goes back to the pool. Since that day, my app stopped crashing that often. Now it still crashes, but less often. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
