In my database, I can see that a query is being executed from both my primary and redundant gateways. This query is on a query tag. I only have three query tags on this system, and all three are showing up from both gateways. The redundant gateway is cold, so why would a query tag be executing on it? This seems like it might be a bug. Surely query tags don't just query the database twice if you have redundant gateways? This can add a ton of unnecessary overhead on the CPU of the database. This is in Ignition 8.1.44.
It sounds like a known bug, SELECTS in Query Tags have this issue, I am editing the title of the post to reflect it.
