Rasa NLU training fails beyond certain Intents (without any error message)

Rasa Open Source

I am using below command to train rasa; core training completed successfully:

docker run -it -v ${pwd}:/app rasa/rasa:latest train

During rasa NLU training, it fails without giving any message as below:

I have noted that the threshold is 425 intents with 4300 + examples. If I add 426 intents in the nlu file, the training ends without giving any error message (as per screenshot).

Can you please advise if there is a threshold (i.e. maximum allowed) on Rasa NLU intents?
