Yikes. That's quite a terrifying response, and yes, absolutely unacceptable.

In particular, there are KNOWN FIB corruption bugs in 12.2SX (I had 
several TAC cases) that are *only* fixed in the 15.1SY train - Cisco 
told me the 12.2SX train was going into long-term critical-fix-only 
mode, which is why we upgraded.

What specific problems are you having, and which exact SY release are 
you on? What mix of linecards/traffic?
