K10 watchdog slows with 100% interrupts

Working with a K10 processor, configured with the Processor Expert and running on MQX. I set up the watch dog and did some some simple test, it seems to work fine. However, I have a bug in my CAN input that generates interrupts 100% of the time. The code I have that tickles the watchdog is starved out and not called. The CAN issue I can fix but I don't know why the watchdog is not kicking in. I can stop and look at the WD registers. I can see the counter is changing but real slow. So if I wait a LONG time, it might timeout. Any idea what can cause this?  Could this have something to do with the PEMicro hardware debugger attached?
