How large is the setting of the virtual memory on your system?
Try to run Tomcat, and then top. Have the system some load, and monitor
the output of top; if the Mem has 0 free and Swap is 0 too, you'd need a
larger swap space.

Why do you have to kill 'em all? The proper way to shutdown Tomcat is
"catalina.sh stop."
But if it doesn't work, you can try "pstree -Gap", and see the root JVM
process' id, then kill -TERM <pid>.

I think you'd have to learn how to write startup scripts. I don't know
what you mean with "Linux 7.1"; anyway, usually the startup scripts
reside in /etc/init.d (or /etc/rc.d/init.d; depends on the distro). On
Debian, there is /etc/init.d/skeleton, that can be copied as a, well,
your skeleton startup script for starting Tomcat.
