roadrunner: [BUG] Workers not restarting after stop

We have a local rr build to run our services with such config file

rpc:
  listen: tcp://127.0.0.1:6001

server:
  # Worker starting command, with any required arguments.
  #
  # This option is required.
  command: "php ./vendor/bin/rr-worker start --refresh-app --relay-dsn tcp://127.0.0.1:6001"

  # User name (not UID) for the worker processes. An empty value means to use the RR process user.
  #
  # Default: ""
  user: ""

  # Group name (not GID) for the worker processes. An empty value means to use the RR process user.
  #
  # Default: ""
  group: ""

  # Worker relay can be: "pipes", TCP (eg.: tcp://127.0.0.1:6001), or socket (eg.: unix:///var/run/rr.sock).
  #
  # Default: "pipes"
  relay: tcp://127.0.0.1:6001

  # Timeout for relay connection establishing (only for socket and TCP port relay).

  # Default: 60s

Actually, it runs Laravel bridged workers. Due to Laravel Nova not compatible with async (it spawns a lot of DB connections and stores some settings in static vars outside the app container), we decided to set max_jobs: 1 until problem is solved. I expected to see this happen: explanation

As for now, I receive error in browser:

1 error occurred:
	* supervised_exec_with_context: Timeout: context deadline exceeded
