Sorry, quickly look at the post and not saw the title of the topic. :-\
I meant that the problem comes from RB 4.9(at least), but it is more than clear to see the title of the post.
I think it will be very difficult to find where the problem is.
It all starts when RB is a nonexistent file, but many times there is no problem and a few this error.
I have noticed that in the report Pety RadioBOSS has been restarted.
Here are the times I've been in front of the monitor, and I saw this problem, only a report was generated. but not a restart.
