TabMon Service won't start and stay running / 2

[11kasper11]

Hello,
I continue in Closed issue 30 (#30), because I don´t know how to reopen it.

I have the same error message in TabMon ""Cannot add non-nullable columns to an existing database table!"", please do have any idea what can be the reason?

We have installed and running TabMon for few years, but this summer it failed with error "Cannot add non-nullable columns to an existing database table!" on two environments at the same time. Resolution was rename countersamples table name in config, new table works! I compared columns in old and new table and everything seems to be the same, so I don´t understand why is this issue...

Thanks :-)
BR, Jan

Same for us, having the same issue with Tableau 2023.3.x and 2024.2.x

If I switch the TabMon.config to csv I do get records written from the remote servers (3 nodes)
