[Vserver] major problem i have no clue where to look

I am not even positive this is due/related to vserver.

I have one guest which is a very busy radius server using a mysql database.

The previous incarnation had no trouble at all on its own machine.

Now, we are missing stop packets quite a bit which is causing radius
accounting to go totally haywire.

I have the added complication that this is a different radius software than we
previously used, and it is not possible to revert back to try the old one.
we previously used IC-Radius and are currently using Free-Radius.. both use
mysql.

I guess my questions would be process of elimination...

1. is there anything within the vserver system that could be considered a
'heartbeat' where a particular guest would be 'off' for a miniscule time
where it could possibly miss an incoming packet?

2. is there anything similar within iproute2 framework?

3. i remember reading somewhere and now cannot find it that there is a way to
increase the priority of a particular guest. i was wondering if i did that for
this one very slightly if it may ease its pain?

4. when inside a guest, does mysql behave slightly slower than it normally
does? if so is there a cure? unfortunately this particular system requires
lightning fast mysql responses.

5. anyone have such an experience and a cure/workaround?
