That looks familiar. Is App 2 Dashboards? To resolve, I downloaded my oldest backup and haven't had problem since. I don't know cause.

Hub going unresponsive in middle of night--Errors with Dashboard in logs

This is the second night that my hub has gone unresponsive around 3:30 in the morning and then had logs with problems with the Dashboards app like this: [Dashboard%20Logs] Unfortunately, it doesn't seem to specify a specific dashboard causing a problem. Any suggestions?
