You can find several different cases in that logfile where it happend, as I have been trying to fix it a few times.
One occurrence is at [1/9/2016 7:12:14 PM] (Line 4094)
It might not be a bad idea to switch the logfile logging in the app.config to "INFO" instead of "DEBUG" by default. logfiles can get huge very fast. People can still set logging level to DEBUG if needed right? Also the error message in the logfile is logged with log level "DEBUG", which would be wrong in my opinion. You should use "ERROR" for non fatal errors, and FATAL for fatal errors that cause program to exit.
In case this might be of use: I used the firmware v 1.0.4, I just updated it to 1.0.5 on my canon 7d Mark II, I will try if that fixed the issue.
