@"fade_dos"#p2567 这个日志表示并没有出问题。

@"fade_dos"#p2569 尝试限制一下运行内存占用

@"johnniang"#p2568 😅 ps 查看进程 halo的进程已经没有了! 这个情况 ,出现了好几次 !用的版本halo-1.1.3-beta.2.jar

@"johnniang"#p2570 好的我试下

@"fade_dos"#p2572 java Xms256m -Xms256m -jar halo-latest.jar

@"fade_dos"#p2586 java -jar halo-latest.jar 有没有异常。

@"Ryan Wang 👍"#p2589 应该是我给他的命令是有问题的，都是 Xms

使用nohup运行halo jar包,正常运行1~2天后,自动停止了? 求助

johnniang

fade_dos java Xms256m -Xms256m -jar halo-latest.jar

fade_dos

johnniang 😂直接被系统杀掉了--->kernel: Out of memory: Kill process 22105 (java) score 314 or sacrifice child

java -jar halo-latest.jar 有没有异常。

johnniang

Ryan Wang 👍 应该是我给他的命令是有问题的，都是 Xms

fade_dos

Ryan Wang 👍 一直用的nohup ,启动正常!

fade_dos

johnniang 我命令后面修改为 nohup java -Xms256m -Xmx256m -jar halo-1.1.3-beta.2.jar >/opt/halo/halo.out>&1 &

fade_dos

Out of memory: Kill process 32174 (java) score 321 or sacrifice child [396674.275735] Killed process 32174 (java) total-vm:2386084kB, anon-rss:336124kB, file-rss:0kB, shmem-rss:0kB
除了加内存,还有什么好办法吗?

johnniang

fade_dos 你这也太惨了吧，哈哈哈

johnniang

fade_dos 我好想进入你的服务器观测一波

fade_dos

johnniang 😂 我1G的内存,查了下内存占用 halo 占了36%左右! 另外装了个mysql mq 占了40%(往上) ,腾讯的监控YDservice占了10% 左右. 然后加上其余的然后很容易OOM,把halo给直接kill掉!
解决方法是把:Mysql给删掉了 ,腾出些内存

Ryan Wang 👍

fade_dos 所以建议用h2啊
