Reflex start abort

[planti]

Hello everyone,
I am developing a simple demo of a RAG application with an LLM and a vector store: LLM on Ollama in the host machine and the vector store in a separate container. I am using the reflex-chat component.
I develop with Visual studio code with the python environment in a container using Visual Studio container development.
Every now and then, I don't understand why, reflex crashes with a "killed" message. I include an example of the terminal screen.
Some details:
Mac OS Sonoma 14.5, M2 Pro
reflex==0.5.2
reflex-chat==0.0.1
reflex-hosting-cli==0.1.13
Python 3.12.3

Any ideas?

@planti if you run reflex run --loglevel debug is there any additional info?

Hi pickleo,
this is the output but I don't understand much more:

@planti does a blank app work for you? I wonder if it's related to some out of memory / other resource error, or if it's a more general reflex issue.
