我对RabbitMQ非常陌生。我收到磁盘限制已满错误，因此我想更改磁盘限制。我依次执行以下命令：
#1. rabbitmqctl set_disk_free_limit 1GB
#2. sudo systemctl stop rabbitmq-server.service
#3. sudo systemctl disable rabbitmq-server.service
#4. sudo systemctl start rabbitmq-server.service --> failing
我看到Rabbitmq进程仍在运行（通过使用top命令）。所以我执行以下命令：
#5. sudo service rabbitmq-server stop
#6 sudo service rabbitmq-server start --> failing
我遇到以下错误：
> Jul 11 15:13:37 sk-backend-vm rabbitmq-server[31810]:

您能在这里帮我吗？我很困。
