They have not completely "gone away", but have definitely improved! When
RadiusNT was on the same box, the CPU spikes would last for several minutes
only to allow a couple seconds of normal activity. Now that RadiusNT is on
a different box, the CPU spikes are still occurring (really odd), but they
only last for a couple seconds at most followed by about 10-20 seconds of

I know you love to hear this question asked, but when will the next version
be available to the public?

This could be an ODBC driver issue.. as you can see above, Radius is much
happier on the outside NT box that is running the 3.50.0305 driver than it
is residing on the 3.70.06.23. As I recall we also had to fight a
malformed packet problem when we first installed it on the SQL 7 box
running 3.70.06.23 that does not exist on the older ODBC driver.
Right now I am spending the weekend trying to build another SQL7 box to
test on. I'll let you know the results.
