When you get into it a little further, you may have to give it as much at 5% headroom. But, if you are now at a lower PWM frequency, then it needs less percentage, just to make sure it gets at least something like 1 us off time per cycle. > Since this is a parameter, I cannot put the gearchange > bewteen the pid and the pwmgen because the pwmgens scale and the > pid.maxoutput limits must be maintained.

NEVER seen anything like that. I would run memtest86 and make sure the CPU and memory are functioning properly.
