I have two Transaction groups, both point to the same Table- Well\_18.  
Group 1: Gets Level Tag every 1 minute  
Group 2: Get PumpVibration Tag every 15 Seconds

When I save, Group 1 is running, but Group 2 Shows a RED X  
The Gateway Log says “com.inductiveautomation.ignition.gateway.web.util.LocalizedMessageException: The data store has reached its maximum capacity”

But I know it has not, as I moved the Tag from Group 2 into Group 1 and it runs OK.

It seems to be a “clash of transactions” - Group 1 updates the Database but Group 2 wants to update its Tag at the same time.

Any thoughts?

What I am trying to achieve is Data storage at different rates for different types.  
I.E. Level - 10 Mins, Speed - 30 Secs, Flow - 1 Min, Vibration - 15 Secs, Pressure - 1 Min
