Hello Rasa Team,

We are using RASA 1.10 and we are in production with our client. It is observed after too many requests the instance is consuming a lot of memory in RAM. approximately 100 request under 5 minutes is resulting 1 GB of memory.

Is tensorflow consuming a portion of RAM for every request? Your input will really help us with further troubleshooting.

I am Having a same type of issue. The problem is that, by default, it allocates the full amount of available memory when it is launched. I see that all 12 GB of the memory is used up.
