840 (Non Solar) Rebooted/Restarted during session

I had the same error on a +110km trip, luckily no data was lost.

Just before the reboot the error message "not enough memory" comes up on the display - but the Edge 840 was in normal naviagation mode.

pls (both of you) post here the content of the error.log (err_log.txt if i remember right ) from the Edge unit (that contains what part of the code was the problem and caused reboot)

same issue today, err_log is empty but the bak (opened in text file) contains:

err_log.txt under Debug is empty. And in the err_log.bak file there is no error on the corresponding day of the mentioned error.

did You transfer your activity profiles from a previous Garmin unit or did You set it up manually (as i always prefer for everybody, do not use auto-transfer or any auto-things )? If it was auto, delete the actual profile(s) and create a new with the same settings manually (i suggest to make photos about data pages and settings, easier to reconfigure everything from a picture imho)

Same error again, yesterday during a tour. Restart of the Edge without warning this time.
I can't find a current error.log in the debug directory, but there is an entry in the backup.

had the same issue multiple times within the last 3 weeks

Hi,

I got the same problem several times in the last weeks. 

as well when I finished a ride and save it. Reboot for no reason. 

what can I do? Any solution?

cheers

Same behavior with the current firmware, in the middle of the planned round is again the error. This time only no reboot but a shutdown - had do restart the Edge840 manually and could finish the planned tour.

Garmin - when can we expect a fix?
