X4 Overheating

Is this camera supposed to overheat and shut off often?

When editing videos if I'm connected to the x4 for too long it will overheat and shut down.

Also when using the underwater case it's the same about 26 mins ish it will overheat and shut down. I was recording at 8k 30 underwater was I not supposed to do that?

Both situations when I turn the camera on again it gives a message saying anomaly detected or something like that

Is this all normal or is something wrong with my unit
