I CAUGHT THE CRASH!!!
I can copy/paste a few entries before and after the crash, but it should be in the log file.
I can copy the terminal buffer and save it as a text file.
The ip ending in .120 is my tablet running Chrome, the .113 is my OpenEVSE charger, and the .103 is the emonpi
Here are the few lines before/after the crash:

end of copy/paste
Notice that the emonpi is still talking to the charger, but the dashboard is not requesting data anymore, and ended with a 404
