I am writing again, bacause it seems that Syncthing crashed again sometime during the night. The problem is that the logfile is just cut off without any specific errors or panics.

After the relay related messages, the logging just suddenly stops.
Are there any specific debug options, which I should enable in order to possibly obtain more information on the crash causes?
On a side note, I have also managed to run the binary without root, but I will elaborate on this a little bit later.
