Our production server has 309 entries in the deferred_bindings table. Some of them date back to March 2015 - but 2 of them, for example, are from about 10 hours ago. I have 2 questions:

1. Why do these entries exist? Shouldn't they be cleaned up automatically?
2. Can I delete older entries / truncate the table or will that lead to data loss?

(The reason why I want to clear the table is that these records seem to be causing very slow queries for the fileupload field.)

Thanks for any suggestions!

I have the same problem too!

October automatically destroys deferred bindings that are older than 5 days. It happens when a back-end user logs into the system.

Destroys all bindings that have not been committed and are older than 1 day:

October\Rain\Database\Models\DeferredBinding::cleanUp(1);
