Hello: Converting from DB1 to DB2... I have a ui-control node that is set to "Connection Events Only" (name = Connect) and another one "Page/tab Change Events Only" (name = Refresh Tab). What appears to happen is that every "connect" event is followed by a "change" event. Then the connection drops…

I would expect to see the Connect followed by a Change, as the client has connected and then opened that tab. I would not expect to see the disconnect, and I don't see that when I run your flow on my system. What version of @flowfuse/node-red-dashboard are you running. If it is not the latest (1.…

[image] Colin: Run top or other system monitor on the server and see if the CPU is being maxed out temporarily. I’m running it local on my laptop. The problem seems to be with that one page. If I change pages and go to another one, it does seem to work. I’m going to let it be overnight and lo…

In the example you posted you are not actually doing anything when the page is switched. In your real flow are you taking action when that page is selected? It may be that which is triggering the connection dropout. Try disconnecting the ui-control nodes from the action and see if that stops the …

[image] Colin: In the example you posted you are not actually doing anything when the page is switched. In your real flow are you taking action when that page is selected? Actually that is one of the problems that I'm having. The ui-control node is on a separate flow and on tab change, it is …

@Colin - I wonder if the disconnects were related to this? https://discourse.nodered.org/t/node-red-dashboard-2-table-tabulator-problems-when-loading-data/98225/2
