Massive Memory Leak on startup

[bnwlf]

Hi there!
I've tried to run asterisk with the provided docker-compose template:

services:
  asterisk:
    image: andrius/asterisk:stable
    ports:
      - "5060:5060/udp"
      - "10000-20000:10000-20000/udp"
    volumes:
      - ./config:/etc/asterisk
      - ./asterisk-data:/var/lib/asterisk
    restart: no

For some reason the container starts filling the 8GB memory of the pi5 nearly instant. This leads to whole system crashes due to fully allocated memory. Does anybody have an idea how to fix that? I have tried it with the latest and stable tags.

Cheers!

I was experiencing this same issue, removing the mapping of ports 10000 through 20000 fixes the issue for me. I think docker isn't happy mapping 10000 ports, even just a thousand ports will make docker unresponsive and increases memory usage substantially

Yes, docker does not like to map such huge amount of ports, I will update docs. Normally you'd need 2x RTP ports per call, and perhaps you'd happy with just 30-50 ports for small business entity/family or 2000 for production system

That's somehow annoying, but I see that it is not solvable form this project's side. Nevertheless thanks a lot for your responses!

No problem! I would look into using host networking for the container. It will map all ports to the host without the memory issues.
