Gateway log flooded with StoreAndForward.Sink.HsqlDataStore Errors

My gateway log is flooded with these errors and I cannot find what is causing them.

Error deserializing data from data store.

java.lang.ClassCastException: cannot assign instance of com.inductiveautomation.ignition.common.sqltags.model.types.DataQuality to field com.inductiveautomation.ignition.common.model.values.BasicQualifiedValue.quality of type com.inductiveautomation.ignition.common.model.values.QualityCode in instance of com.inductiveautomation.ignition.common.model.values.BasicQualifiedValue

Did you upgrade from v7.9 with data in the store & forward cache?

Yeah I bet there was a few sets in there, so dump it?

4

Yeah, all kinds of data types were refactored, and serialization doesn’t like that.

I’ll give that a try, thanks @pturmel

So I deleted all the quarantine records but it didn’t make a difference in my logs, still 100s errors every minute. Is there a better way for dumping the store and forward cache?

7

Not sure. Support could probably tell you which SQLite file to delete…

I had a similar problem where deleting quarantine records didn’t work. The steps in this post did fix the problem. It was a dev environment for me, so I wasn’t worried about loosing some data. That may be a consideration for you.
