Hi, how are you? I have a problem in my application with zk 8, when opening more than 5 windows, I don't execute the cleaning method of the DesktopCleanup class. The browser features are: Internet Explorer 11 Windows 7. The same application with zk 5 I have no problem works correctly.

Does this only affect IE11 or also other browsers? Are you using any kind of comet server pushes? Some browsers have tight connection limits possibly blocking the rmDesktop request when a browser closes during onBeforeUnload.

thank you very much, the topic is just what you say, internet explorer 11 has limit connections.

ok if you're running into such limits, then you can limit the number of desktops per session.

https://www.zkoss.org/wiki/ZK%20Configuration%20Reference/zk.xml/The%20session-config%20Element/The%20max-desktops-per-session%20Element

E.g. if you limit this to 5 then older (LRU) desktops are removed when you open more than 5 browser tabs. At least this ensures your DesktopCleanup listeners are called, even if the browser can no longer connect and send those "rmDesktop" requests.
