In our Production ZK6 application running on Tomcat7, we have started to see our logs filled with this exception. It does not mention our code really in the exception so I write here today to see if anyone at ZK understands what this error "Unable to activate destroyed desktop" might mean. Thank you!

SEVERE: Exception Processing ErrorPage[errorCode=500, location=/zkau/web/org/ourapp/ui/zk/errorLoading.zul]
org.zkoss.zk.ui.DesktopUnavailableException: Unable to activate destroyed desktop, [Desktop z_9di:/org/ourcompany/ourapp/security/impl/loginWindow.zul]
