As others will surely tell you, there is something amiss in your
application that spawns threads. However, the maximum number of
threads Tomcat will handle is somewhere about 2400. So, if you are
getting an error at 1000 threads, look somewhere else.

There are some thread-specific parameters you can play with, in

factor moves the limits on others. Your best bet (assuming you

Why don't you
Well, since you asked...

a privileged port and which is distributed with the Tomcat archives.
Did you use it?

We have no reason but the port to give the tomcat-user any

Thank you for the suggestion. I will investigate.

Tomcat does not require you to run it as root in order to use port
443.
There are various techniques, including using a web server such as
Apache httpd to front Tomcat, iptables (or similar) tricks to re-route
