After a second glance I have to state that the problems of the faulty 352 are not completely solved. The message window containing "Do you want to wait 30 more seconds to finish the request?" is still a true companion. It seems to pop up after a while when I leave the web UI open in the browser. No matter if flow monitor is open or not, simply staying on the dashboard view.
And the other one "Do you want to wait another 30s...." pops up too from time after time.
This is somehow a cosmetic issue, but who can tell if there are other issues under the hood which are not so obvious? My trust in this system dimishes from update to update....
