OMC cloud agent 安装之后经常停止
发表于：2025-11-08 作者：千家信息网编辑
千家信息网最后更新 2025年11月08日，使用客户的测试账号做一个OMC cloud agent的测试，agent 也安装好了，日志也自动收集上来了。第二天发现agent 停止服务了，于是就给启动了一下，状态也正常，下午发现又停了。看来是有问
千家信息网最后更新 2025年11月08日OMC cloud agent 安装之后经常停止使用客户的测试账号做一个OMC cloud agent的测试，agent 也安装好了，日志也自动收集上来了。
第二天发现agent 停止服务了，于是就给启动了一下，状态也正常，下午发现又停了。
看来是有问题了：

初步看是java虚拟机的内存不够，到metalink上看看，也查到了同样的问题：
