Scale-Out Architecture & HistoryManager Errors

Hey folks,

Ignition 8.1.2.

I’m working with a client with scale out architecture. At the moment it’s just two servers, the tag server and the client server. The facility from 7.9.13 to 8.1.2 in early February and made sure to add the read-only Tag History license to the client server.

However, it appears as though they’ve been collecting the following errors on the client server every minute since the upgrade:

Is there any way to determine the source of these errors? The system has run in this configuration for several years without error on 7.9, having a hard time determining what changed.


Is one of these an Edge server?

Either way, you may just need something added to your license. Best to contact support.

Neither are an edge server. I’ll reach out to support.
