Grafana dashboards freezing and crashing


I have some Grafana dashboards running on MS SQL Server 2016 to retrieve data. These dashboards will crash periodically and they are only using the standard singlestat, graph and discrete panels.

This dashboard was on a refresh rate of 30s and I wound it back to 1min to see what impact this would have.

What could cause Grafana to crash? Chrome shows up with the typical ‘Aw, Swap!’.

Is there anything that I can look for? Memory usage?

The version of Grafana is v5.3.4 (69630b9) and I am aware we can upgrade to a later version. I need to make sure the current panels are supported before I can upgrade.
