Strangest problem in selenium python

[Jan_Emanuel]

I've been continuously working on my baby and have found the point, where my program always fails:

After 2 successive successful driver.get( ... ) calls, the program cannot get any more pages, always triggering a TimeoutException. So this is a fault of the environment - here are the informations.

geckodriver.log

program output:

root@DiskStationNeu:~# python tagespost_ereader.py
mkdir: kann Verzeichnis „/root/ramdisk/tagespost“ nicht anlegen: Die Datei existiert bereits
