请教存在o2oa应用异常直接停机的问题

fangchengshi

反馈一个问题  ，凌晨备份数据执行完成之后，应用直接关掉了。早上才发现，查看日志如下，【2020-04-30 00:41:42.974】之后没有任何的信息了，启动后，没有发现异常。
服务器是华为云上面的【Linux version 4.4.0-166-generic (buildd@lcy01-amd64-020) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10) ) #195-Ubuntu SMP Tue Oct 1 09:35:25 UTC 2019】 ,数据库是mysql，服务器日常负载比较高，cpu平均占用在30左右，内存在98%左右。
服务器刚迁移，但是29号凌晨没有出现异常停机。

您好：从日志中，无法判断是什么原因导致的问题。
是否能重现？

谢谢

如果您的服务器，经常99%-100%，建议扩容。
不过内存降低后，如果没问题，可以再观察观察！我们也和技术部门反馈，是否是性能导致的问题。

可以重现，两三天重复出现。
日志我没有都看，看两次日志，都是一样的，直接关了，没有记录异常日志。可能是o2oa如果在操作系统内存达到99%-100%会出现严重异常，导致关闭，并且不会关闭日期。

我把操作系统其他应用关闭之后，内存占用降低到50%几天内没有再出现这种问题了。
