C5510 resetting when I set an int to 0



I get the following in the CCS Console when I set an int to 0 while JTAG'd into my DSP.  :/  

C55xx_1: Trouble Reading Memory Block at 0x1a0eb on Page 1 of Length 0x1: Error 0x80000002/-1143 Fatal Error during: Memory,  The memory at 0x000341D4 continually indicated it was 'not ready' All memory operations currently in progress were aborted in order to regain control of the processor. This is considered a catastrophic event, but the debugger should  still be able to access memory and CPU registers.

This design has been running really well for some time now.  We added a bit of code to introduce a low pass filter on our signal using cfir from the DSPLib.  But this code is nowhere related to that.  This is initialization code at startup when I set various tracking variables to 0.  
Here's the CRAZY part.  We have 2 DSPs in the system.  Both are C5510A's.  DSP0 runs fine.  DSP1 crashes.  The behavior is identical across multiple boards.  It used to run great.
Can anyone shed some light on this error and help me understand how I should troubleshoot it?
