Tags disappearing on restart

Ignition
1

So my tags disappeared twice today.

I have a bunch of tags within the default tag provider. When my memory utilization hits 90% and everything stalls, the gateway has to restart that's when I notice my tags disappearing. After I restart the gateway, and I relaunch the designer I see all my tags in the default provider gone.

I do have audit logs but it does not tell me anything and the gateway logs does not tell me anything either.

Does anyone know the cause or how I can find the root cause? I don't want to keep reloading backups.

Have you checked your hdd space? I've certainly seen strange bevahiour, saves to views and the entire views just vanishing and the cause was 0 MB free on the gateway.... Very nice

Yes, I have a lot of space left.

I'd interface directly with support on this one. This seems like something they would want to dig into.

Hello. Did you figure out anything here?

We are experiencing similar issues where after a restart old tags reappear and the newly created tags disappear.

Seems like the new config is only held in memory and after a reboot a persisted config is restored.
We use the APIs to write in all tags.

Their post was from a while ago around a time there were some bugs that may have been responsible for this. I've seen a similar problem on redundant systems and I know that problem has been fixed for a while.

If you're having this problem and not on a fairly new version you may want to consider upgrading to a newer version to get any bug fixes.

You can also always contact support to get some help on it.
