eucalyptus-cloud.service 4.4.4 不断因 JVM 内存错误而崩溃

Question

我正在尝试完成手动安装指南。当我为控制台 (euare-accountcreate) 注册管理员帐户或注册服务 (euserv-register-service) 时，桉树云服务不一致地崩溃并出现相同的 JVM 内存错误。例如，有几次我已经能够注册 UFS 或创建管理员帐户，但是当我继续执行安装中的另一个步骤时，它将失败并且检查服务状态显示它已崩溃。我没有处理 Java 内存错误的经验，可以真正使用一些帮助来了解发生了什么以及如何调查一般的此类错误：

编辑以包含一些版本信息：

[root@cloud ~]# cat /etc/centos-release

CentOS Linux release 7.5.1804 (Core) 

[root@cloud ~]# java -version

openjdk version "1.8.0_181"
OpenJDK Runtime Environment (build 1.8.0_181-b13)
OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)

编辑以注意我的困惑点：该系统仅使用了 25G RAM 和 223G 空闲内存。所以我需要帮助来理解 java 是如何运行内存不足的。

试试这个修复：
