Joypad problem

Hi,
My CNC machine has been working well for last few years now - many thanks to all the linuxcnc developers!
I do have an intermittent problem with the joypad, sometimes after axis has started if I press an axis enable key the axis starts moving without a velocity command. It is as if the deadband on the axis has shifted or is not enabled.

Rebooting / plug unplugging the joypad normally fixes it, however it is annoying and I'm not sure how to debug what is going on.

Any help will be appreciated.

Here's my conversion

Hmmm thanks this sounds very similar. I shall try and monitor as shown.
Thanks.

So after a long gap the problem is back, this is what I see in the shell window. Linuxcnc runs ok for a while then the error appears and the joypad doesn't work anymore.
