This points more to an UI exception rather than engine one. Please install the webadmin-debuginfo package (please make sure in the same version as the webadmin itself), restart the engine and reproduce again and attach the /var/log/ovirt-engine/ui.log

According to the comment1, installed webadmin-debuginfo package [root@rhvm41-vlan50-beta ~]# rpm -qa|grep debug ovirt-engine-webadmin-portal-debuginfo-4.1.0-0.1.beta1.20161201090635.el7.centos.noarch ovirt-engine-userportal-debuginfo-4.1.0-0.1.beta1.20161201090635.el7.centos.noarch Reproduced and attach the UI log
In logs I see: "$wnd.jQuery is not a function" which seems to be the reason why the UI stops reacting. Moving to UX for more investigation.
Alexander, can you take a look?
Sure, The message seems to indicate that jQuery is no longer available, which is obviously really bad. To the report does the following 'fix' the issue: When the UI is unresponsive, and you reload the UI (press the refresh button in the browser), does the UI start working again?
Indeed (In reply to Alexander Wels from comment #6) > Sure, > > The message seems to indicate that jQuery is no longer available, which is > obviously really bad. To the report does the following 'fix' the issue: > > When the UI is unresponsive, and you reload the UI (press the refresh button > in the browser), does the UI start working again? Yes, after reload, the ui can start work again. I had to say above issue can be only found in that build 4.1.0-0.1-beta1.20161201090635.el7.centos, when I upgrade to rhv-4.1.0-3 or later, never reproduced it.
So if it doesn't reproduce afterwards, I close it as worksforme.
