Ok so..

I checked the reverse DNS on each of the vserver's and they have no problems
performing reverse DNS, they respond back pretty quickly in fact.

Maybe it's a memory or file handles thing like you suggest I guess I have a
2 fold question, where would I look for such things and how. Linux pretty
much uses all the memory you throw at it so top is not very helpful.

Secondly is there some sort of 'rule of thumb' to figure out how many VPS's
you can run on a specific type of server CPU/MEM type calculation?

Any suggestions would be greatly appreciated.

This isn't a feature. You have a problem; I occasionally see this on one
box, often when it is under heavy load (or even just before it is about to
`hang' in the way that everyone else describes. ;-)

Check file-handles, check out-of-memory, check if the box is actually doing
some work; in a similar but different problem, check whether any of the
daemons are trying to do reverse lookups.
