MOVI EVENT CODE 211

I am trying to train 511 short sentences. Sometimes it works OK, but most of the time, when recognizer.train() is called, I get “MOVIEvent[211]: Sentence added to cache.” , and no training is done. I cannot fine that code anywhere. Is there a list of event codes that includes all of the events? The user manual says that 200-299 are responses to commands, but the command documentation for train() doesn’t mention and codes.
