Store and Forward Items Dropped

Ignition
1

Just a few have been dropped… Not sure how to diagnose this. Also not sure what the 195% value is representing. Is that the local cache?

Why would there be so many items dropped?
Usually they’re a “quarantined items” retry button, but there don’t seem to be any buttons in order to resolve the 195% capacity issue

Getting constant errors like these as well:

StoreAndForward.Sink.HsqlDataStore

Did you recently upgrade Ignition versions? Or send data across versions?
It’s not being ‘quarantined’ because it’s not an issue with the DB - it’s an issue with S+F/Java serialization…

We upgraded from 7.9.15/16 to v8.1.0 approx 2 months ago. I didn’t notice these at the time, but I can’t say that I was looking at the logs then.

4

Do you remember what version you upgraded from? Or, better, do you have a .gwbk from before the upgrade (and a current one) you can send in to support?

5

Yep, I have all three. ~220 megs each backup though. I’ll create a case and upload. Cheers.

Anything I can do in the meantime?

You can try deleting the entry for that DB in the datacache/ folder in the install directory - you’ll want to disable the DB/disable disk cache for it, then delete (or rename) the entire folder, then re-enable.
If it’s some kind of old data issue, then I would expect it to go away. If it’s somehow coming from in fresh, then that’ll likely tell us something as well.

Well that appears to have resolved the errors in the log file. I’m not getting them anymore which I assume is good :slight_smile:
