PAServer using 100% of CPU in docker-compose

[silvioprog]

Hi.

Steps to reproduce the problem:

1. Create a file called docker-compose.yml with the following content:

version: "3.6"
services:
  paserver:
    image: radstudio/paserver:10.3.2
    container_name: paserver
    ports:
      - 64211:64211/tcp    
      - 8082:8082/tcp
    restart: on-failure

2. Run the following command:

$ docker-compose up

3. Attach a shell to the container:

docker exec -it <ID> bash

<ID> = The container ID, e.g.: docker exec -it bbb5cb400d07 bash

4. Inside the container, use the top command to watch the processes:

$ top

Now, notice the PAServer using 96.7 ~ 100% of CPU, e.g.:

For this not to happen it is necessary to enable tty: true
