the NPE-G1 is already supported in 12.3 mainline.

true, but virtual-access subinterfaces are even better to address this
problem as they're lightweight interfaces not needing as many resources,
so there is no need to pre-clone these. Unless you're doing something
fancy in the Radius profiles like access-list or "lcp:interface-config",
you should be fine using VAI sub-interfaces. Try "test virtual-template
1 subinterface" and check if any command on your vtemplate prevents you
from using subinterfaces. Then I'd remove the pre-clone command and
check if users start to use VAI sub-interfaces.

In addition, you want to enable "radius-server source-ports extended"
(to allow for more than 256 concurrent outstanding Radius requests),
enable "radius-server deadtime <min>" to active a more apppropriate
dead-server detection algorithm for this environment, and you also want
to watch your input queues when many uses try to login at the same
time..
