How do I see if there is an open socket? But in principal I have found the problem. (Not the reason.) The problem is Firefox. (So it is not bottle and also not AngularJS.) When using Chrome there is no problem. Not even when I do 15 times a refresh. With Firefox there is this problem. Even when I restart it. So I have found the problem and it is certainly not a Python problem. I should post it on the Firefox, but if there will be an use-full reply … I have been reading it for a long time. And when someone mentioned that Firefox used to much CPU or memory the replies where in my opinion not very helpful. It even happens with Firefox in safe-mode. Less often and not two times, but max one time. Well, first some sleep and then trying to get something useful from the Firefox mailing-list. ;-) -- Cecil Westerhof Senior Software Engineer LinkedIn: http://www.linkedin.com/in/cecilwesterhof -- https://mail.python.org/mailman/listinfo/python-list
