>all of the Tomcat threads are waiting for db connections to become available
So that implies that Tomcat only supports a max of 3 threads... I uncommented: <Executor name="tomcatThreadPool" namePrefix="catalina-exec-" maxThreads="150" minSpareThreads="1"/> in Tomcat's server.xml. But I still see the problem when I cap my db connection pool at 3. I would think that I should be able to increase the number of threads available to Tomcat to prevent this problem (I'm not saying that is the correct solution to my problem - I fully understand that our design is the root of this problem). -- View this message in context: http://www.nabble.com/Tomcat-thread-pool-question-tp20915752p20939919.html Sent from the Tomcat - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
