XPRO2 red line lock up "Turn off camera" error?

I have one of the first batches from b&h, just wondering if anyone has had this error? XPRO2 red line lock up "Turn off camera" error?

I have had it several times, today I shot a wedding and it must have locked up at least ten times, different lenses and a fresh battery, still happened. Ideas? Suggestions? I shut it off and turn it back on and it works but it makes me nervous during a wedding.
