canal-server运行一段时间自动停止

canal-server运行了大概十几天，突然自己停掉了，下面是两个log的输出 canal-log： 2021-09-23 11:07:11.076 [Thread-6] INFO com.alibaba.otter.canal.deployer.CanalStarter - ## stop the canal server 2021-09-23 11:07:11.175 [Thread-6] INFO com.alibaba.otter.canal.deployer.CanalController - ## stop the canal server[172.17.0.3(172.17.0.3):11111] 2021-09-23 11:07:11.187 [Thread-6] INFO com.alibaba.otter.canal.deployer.CanalStarter - ## canal server is down.

没有输出报错异常之类的信息，就像是自动停止了一样，mysql里面查监控的连接也没有了 输入ps查看canal-server/bin目录下保留的pid也没发现 不知道为什么会自动停止，有没有大佬帮分析下原因~
