This indicates to me that your power supply(ies) are overloaded.  We had
this happen when we got just over half of the chassis full of cards. 

Ascend now makes 2 type of TNT power supplies.  The older one can only
handle about 6-9 cards (depending on type) with a single power supply.
Once it starts shutting off, you need to add the second power supply or go
to the newer ones.

This is fairly well known, but Ascend has trouble admitting that they so
badly engineered the original power supplies that they may give you a
run-around before telling you the truth.
