I executed post request on https://databus.dbpedia.org/api/publish in the loop in python script and I received that error 2 times out of 44 times

@jlareck this could be due to a file size (body of the post request) being too big.... maybe we need to adjust configs of Apache for that... could you check if it is due to a file size? How big is the upload data size for the requests which fail? Do the random requests fail when you execute the loop or particular ones?
