Hi Mark, But that would have been the problem even earlier when Tomcat was listening on all available ip's on the machine. If not listening on two port's may be we should try to use IPv6 loopback rather than Mapped IPv4 address when IPv6 is Enabled. That would be inline with apache's resolution of localhost as well.

That gets messy, quickly. What do you do about the thread pools? Split maxThreads between them somehow? Use an executor? I think it is better to leave that to the system admin. I would expect "localhost" to resolve to the same thing for both httpd and Tomcat. There may be more mileage in figuring out what this isn't the case and solving that problem.
