There is an alternative strategy which allows you to run as any user and bind
to restricted ports.
This can be done using authbind. Authbind works with the JVM using native
threads and requires no native code. It allows quite a lot of control over
which ports can be bound.

I finally came around to writing the threads for each session that
the Pop Server will handle, I tested it and despite 'x' sessions
spawned, 'ps' would show just one process in the list. But this was
when I used the green option. However, when I used -nat

Why are you concerned with memory leaks at all? Sin

Hi Yavor and everybody else,
Thank you for the detailed replies.
Everybody advises writing a script to run the Pop Server,
in more detail -> using SysV Script , nohup to dissasociate from the
terminal.
So heres the framework for the Java Code

2> Release Root Prive
