Pool overlaps with other one on this address space

[juggy]

I try to get 40 agents working on a beefier machine on EC2. My setup calls for 4 services running on docker compose. When a full run is running, there are maybe 30-35 concurrent steps. When it starts, I get this error for each step:

$ docker-compose -f docker-compose.yml -p buildkite5b8fb2692e7846369dfe5f795769144c -f docker-compose.buildkite-197-override.yml up -d --scale backend=0 backend
--
  | Creating network "buildkite5b8fb2692e7846369dfe5f795769144c_qms" with driver "bridge"
  | ERROR: Pool overlaps with other one on this address space

I tried creating and assigning a custom network to the services like so:

networks:
  qms:
    driver: bridge
    ipam:
      driver: default
      config:
        - subnet: 10.10.0.0/16

But without success. Am I missing something in my configuration or is there something missing in this plugin to make this work?
