I don't know. I haven't found any causes for the failure, and no solid repeatability. However, sometimes only some of my Jaguars will work (which is why I made the startup test). A Jaguar may spontaneously start working several minutes later.

I used to think that this was due to occasional watchdog timeouts. However, enabling control to the Jaguar does not help, and a watchdog timeout does not disable control to a Jaguar (it just cuts out the heartbeat).

Is it always the same Jags which sometimes don't work ?

Try swapping them with Jags that always work and see what happens.

I'll record which Jags it is next time it happens.
