Vera Lite UI7 unresponsive

Hi All
I had AutoVera installed on my Vera Lite UI7 (Firmware1.7.481) for just over a day and I noticed that after some interactions (switching the Fibaro switches on and off a few times) Vera becomes unresponsive. Now I am not sure that this is AutoVera’s fault but after uninstalling the app the problem goes away.

I have quite a large system with many plugins and lots of devices, so it could be combinations of things.
I do like the functionality that the Auto + Tasker ecosystem offers so I would like to get it going. How can I troubleshoot this problem?

Thanks
Ben
