I am having a similar problem.  At first, I had 1 tnt rebooting itself
every few hours (always it seemed at peak traffic times) and the only
errors I would get would be related to the ethernet card.  Now I have
another TNT doing the same thing.  Both are running 7.2.3 TAOS, both have
the 4 port ethernet cards.  They are on different networks connecting to
different radius servers.  The TNT that has just started acting up has
much lower usage (about 70 users at peak time) than the other TNT (400+ at
peak time).

The problem first appeared last week and has now spread to another
machine.  I have one more TNT that isnt doing this and a bunch of
max2024's and max4048's that are fine.

Very frustrating.  Anyone else care to chime in?
