Hi Osama...

About your memory question, not all the process(es) appears in "top"
because they are "threads" and not a stand alone "process".  Threads
counts in the memory, but the are redundant, they should be counted only
once.  This is were the confusion comes from.  Don't give it a thought.
If you need more info about this subject, search for "Linux Threads
Memory Count".  This is a known bug/feature of the Linux Kernel that had
been discussed a lot.

And about your problem with LimeWire, which version you're using and
what is the version of the Java (and where did you get it)?

Ziyad.
