Great, ER11 is ok.
I was able to stop cache, start it again and for example issue reset statistics operation too.

This was something more like "smoke test", we need to test all operations (could be time consuming because of setting proper environment - for example for X-site ops. etc.)

Setting this as VERIFIED, problem solved, thanks!
