Question mark error emails, any ideas?

Greetings All,

I have been getting these weird errors from MYBL whenever it is under some use. Since the new firmware it has decreased drastically and I only get them under heavy use so I have figured that it is temprature related but it is still odd and I am hoping someone else knows of it. The unit has a lot of fresh air around it so the only other way I could try to get rid of this error is to make it sit higher up on the stand. Below is a copy of the error:

The ??? emails are usually thermal warnings.
