@nminchin did you ever get an answer on this? I'm having the same issue on 8.1.7 and I'm wondering if upgrading to the current version (8.1.22) would prevent this from happening.

I see you've had similar issues regarding this [here](https://forum.inductiveautomation.com/t/easychart-stops-displaying-data-periodically-new-entries-randomly-added-into-sqlth-scinfo/43280).

Anyone from IA want to weigh in on this one? @paul-griffith ?
