Hi Matt,

Nice printout. Is this from the commonly used iocStats module [1]?
You seem to be facing an underflow effect of a 32bit unsigned that is being converted to double.

Cheers,

We're running EPICS 3.14.12.7, RTEMS 4.10.2 on the mvme3100 bsp.​ We just added a small support module to calculate cpu statistics.


We're seeing corrupt calculations on some threads. Has anyone seen this? Any advice?

Thank you,
-Matt
