[Bug] Model performance degradation after updates: excessive iterations and livelock behavior

Bug Description
Stop playing around with the models, before or after an update, for some reason, they start performing extremely poorly: long waiting times, poor responses, multiple iterations doing the exact same thing - looks like a never ending pool, livelock.
