Hi Karthik,

Evidently the software isn't perfect after all.

I would suspect you have an interaction between interrupts, where there's a rare case where perhaps interrupts should be disabled, but aren't.

I ran into a case where I had set a flag, and immediately tested it...but if an interrupt came in between the two (and every long once in a while it did) the test result wasn't correct and things didn't work right. A simple disabling of interrupts during this piece of code fixed it.

Somewhere in your massive amount of code is lurking a tiny timing problem that's just waiting to be found.

Good hunting!
