Couple of strange lockups on EM1

So this past weekend I was shooting the Superbike racing at Barber Motorsports park and used my EM-1 for the first time for motorsport photos. The camera did pretty good (see my other thread here https://www.mu-43.com/showthread.php?t=66140) but I had two lockups.

The first time i was shooting the grid on the track which essentially is shooting the riders as they are waiting in their positions on the track before taking off. No fast motion or high speed continuous shooting. I clicked one off and then the screen (EVF) froze. In this case i was able to turn off the camera and back on and it continued on just fine. This has happened once before since I've gotten the camera and i don't think too much of it as it is infrequent and it is a very complex camera and the occasional reboot doesn't seem out of line for a camera that is mostly computer.

Later that day though as the last race was beginning I fired a couple of shots as the bikes were doing their warm up lap and then the shutter started clicking at very high speed (like 8-10 fps). I wasn't holding down the shutter and no photos were actually being taken. Also turning off the camera did not stop it so i had to pull the battery. Overall the whole thing didn't last more than 2 or 3 seconds but this was a bit more concerning than the standard frozen screen. Has anyone else experienced this issue or heard of it?
After putting back in the battery the camera behaved normally and I ended up shooting around another 300 or so images without incident. Everything does seem to be working fine again but if this type of issue is indicative of a known problem I want to get it taken care of before it doesn't self correct from a battery pull.

 

Yes, at 1.4 I believe or what ever one it was that came out a few weeks ago that was causing grief for the EM5 crowd. I'll have a look at see what's current to make sure.
