docker-compose down failing: Too many open files

I'm using docker-compose in my production server. On my deploy process I run docker-compose down, deploy the application and run docker-compose up. However when I do docker-compose down it returns something like that:

ERROR: for ubuntu_php_run_1105  ('Connection aborted.', error(24, 'Too many open files'))

ERROR: for ubuntu_php_run_821  ('Connection aborted.', error(24, 'Too many open files'))

ERROR: for ubuntu_php_run_820  ('Connection aborted.', error(24, 'Too many open files'))

If I run this command manually more times eventually it succeeds but I need to fix it because this error makes my deploy process to fail.

It seems to exceed maximum open file descriptor of the container, tries to increase the maximum number of open file with nofile of ulimits.

For example,

ulimits:
  nofile:
    soft: 98304
    hard: 98304

For command line

--ulimit nofile=98304:98304

I figured it out... I'm running some jobs in background to do it I used docker-compose run [service] [command], everytime it runs a new docker container is created and not killed. When I tried to docker-compose down there were a lot of containers and docker halted.

To solve I added --rm flag in docker-compose, this way when the command finished the conainer is removed:

docker-compose run --rm [service] [command]
