Already familiar with this, and I don't think it applies here.  The 
outgoing interfaces are not congested (outbound rates of 40-100kbps on a 
T1), yet the router appears to be dropping most or all traffic headed 
out those interfaces once the "magic trigger" is pulled.

I'm starting to suspect the PA-MC-2T3.  We had an episode where EVERY 
T1/frac T1 dropped line protocol (PPP or HDLC) simultaneously.  A week 
later, we had the scenario mentioned above, and it's recurred twice 
since then.  It's always been the same slot/PA that's been affected, and 
the companion PA-FE-TX doesn't appear to be afflicted at all.

Any other thoughts?

Thanks for the help!
