Hello.

Ive created a custom cluster - m4.large. When i try to execute some code in this cluster the behaviour is as follows:

- Cluster starts, have running status

- I run code, for example print("Hello")

- Code runs indefinitely

- I click interrupt, it stops after long time

- When code is stopped, next code execution runs fine

But this is about python, SQL dont run at all, even SELECT 1; query.

Can someone tell me what can be an issue?
