Hi,
we noticed the following strange behaviour on our instance:
One user copied pages some days ago. Today he just opened one of this pages, no editing or other changes. Since he opened the page our log gets thousands of these errors:

The performance of our instance went down since then. We restartet the system and now everything is fine, but how long? We have no idea what caused these errors and how to prevent them ...
Has anyone here? Thanks!
