For number 1, that log message looks like a Vision client opened for project PackingStation.
For number 2, that log message can occur when you have a tag configured to store tag history to a historical provider that is disabled. If you check Config > Tags: History, is your “milroom” provider disabled?
Number 2, my millroom source is enabled. I was running on a temporary gateway until I fully converted to v8.1 from v7.9. I downloaded a gateway back up from the temp and imported it to my production gateway (both used the same DB connections). That is when I started to see this message.
I should have come back and posted the answer .
For us, the problem was a logout script that was running based on inactivity seconds. We have a default, read-only user that is logged in after a certain amount of inactivity, but there was a bug in the logout script. It wasn't looking at the current user, so after the client switched to the default user, it kept logging the default user in everytime the timer script was executed.
