Thanks a lot, Ken, for your reply.
Ubuntu 16 in a VPS M SSD (no setup)+ (CONTABO)
Yes I have checked that questions.xml files increasing in size, see attach
What could be the reason for that to happen?
I had noticed that recently I wasn't able to duplicate a question, it hanged Moodle. So I could imagine that it tried to duplicate all the question bank, could be it possible?
How could I delete all the duplicate questions?
