There are the obvious limitations of the number of ports available on your platform (I believe there are 64k ports on most TCP/IP stacks), so that shouldn't be a problem. Then, your particular user and/or process may have limits placed on the number of ports you are allowed to open. This is usually something like 1024 or so, but you'll have to check with your local system administrator. Something I ran into when doing load testing is that you can also run out of file handles when many connections are open (this is all connections across all <Connector> elements). So, if you have a file handle limit of, say, 1024, and you have 100 <Connector> elements and each of them is configured for 10 connections, you have 100 * 10 = 1000 total connections, each of which needs a file handle. Tomcat itself maintains many open file handles (for things like JAR files, log files, etc.) and it's very easy to hit the 1024 file handle limit. This is just an example: you may have many more file handles available to you, and they are almost certainly configurable so you can increase them if necessary. > The reason I am asking all this is we need to implement the same on our > production server and I need to be aware of any issues that could arise with > this method? I would be sure to test this configuration on a separate server before deploying to production. Always double-check things like resource limits on the production server before attempting to go live: there's nothing worse than having to back-out a build to production.
