IRQ pin not tripping interrupt

Using the SMAC 4.1a simple network template, with a M9S8GT60 processor, my remote (rx) works for a period of time, (from 1 min - 3 days) then suddenly locks up.  This only happens if it is recieving communication on the same channel. (ie I shut the tx off, & it runs fine for 1 week +).  I have managed to capture with BDM what is happening when this happens, & the IRQ pin is driven low (verified on a scope) but the Interrupt flag is never set. I've tried (IRQSC = 00010010) and (IRQSC = 00010011) .  If I manually change the IRQMOD register, the module recovers, but I'm not sure how much of that is related to the BDM.  Any Suggestions?
