When I use Supervisor to run a command to subscribe a Redis channel, I get the Redis exception with 'read error on connection' message.

To solve it, I have to set default_socket_timeout to -1 before subscribing channel. PHPRedis uses the PHP sockets, which will timeout after a set amount of time.

Example:

#[NoReturn]
private function subscribe()
{
    ini_set('default_socket_timeout ', -1);
    while (true) {
        try {
            Redis::connection('bc')->subscribe(['created-contract'], static function ($message) {
                logger()->debug("Created contract publish message: $message");
                dispatch(new SendNewContractNotification($message))->onQueue('notification');
            });
        } catch (Throwable $exception) {
            logger()->error($exception);
        }
    }
}
