Hi all,
Is there anybody who has a LinuxCNC instance that runs for more than
(multiples of) about 49 days at a time (that is for a 1kHz servo-thread)?
There is a race condition when a 32-bit heartbeat counter wraps. It can
only be hit every ~49 days within a time window of one servo-thread
period (usually 1ms). So, the chance of hitting the race is very remote
and can only be hit if you are actively tracking the heartbeat variable,
which usually nobody does.
So, does it need to be taken care of or should it be considered academic?
