Yes. An occasional blip at the T1 level, (mostly do to CLEC icompetence 
and all accounted for) but over the past two weeks since we moved them 
they are running clean and solid on the 7206.

However, I fail to see how a T1 running errored can affect an entire DS3?

They are at minimums. Been there. Done that.

Replaced the VIP to.. that didn't solve it either. However, the 
difference bettern a PA-MC-T3 and the 2T3+ is a lot of engineering. What 
firmware reveisions are you running in your PA-MC-2T3+?
