I have problem using Tag Pens for Easy Chart. Every about 45 minutes an error appears like this:

That suggests that the SQL Server is underprovisioned and struggling to supply these chart queries steadily while other stuff is going on.

If your SQL Server is on the same machine as the Ignition gateway, fix that first.

If the SQL Server and the Ignition gateways are in separate VMs in the same hypervisor, ensure that the hypervisor is not overcommitted for either RAM or CPUs. (That's when the CPUs or RAM allocated to all VMs is greater than the physical total available.)
