Unfortunately, this is not a jvmtop limitation/bug but a security restriction 
built in the (target) JVM to prevent other users to get insight in processes 
which they don't own, root included.

For the same reason you can't connect to these processes neither using the 
official monitoring tools like jconsole, even under root.

There might be a chance to spoof this security security check if jvmtop is 
running under root however further investigation is required to see if this is 
possible at all.

If you want to help you can look at the following question which is describing 
the details for such a spoof:

One point about your response (thanks by the way), with root I can connect 
JConsole to all JVMs on the system, regardless who the owner is.

I just tried this - and you're right, it definitely works - at least on linux 
and the oracle jdk 6.
Thank you - no idea why I had this incorrect fact in my mind.

I'll investigate this further - stay tuned for an update.

Can you please retry this (under root), using the release candidate: 
http://jvmtop.googlecode.com/files/jvmtop-0.4.2.tar.gz

Thank you sir!!!  It works perfectly!
I tried both the regular and detailed view, and as long as I am root, I can 
attach to everything.

I will definitely keep an active watch on this project as it is very good for 
my needs.

Regards, Nic.
