Amazon ec2 如何修复sonarqube服务器6.7.2.37468上的内存不足问题

当Sonarqube服务器版本6.7.2在AWS EC2实例上运行时，大约每月一次，出现内存不足错误，服务器关闭，我们需要手动重新启动，OS/JRE级别或应用程序服务器级别存在内存泄漏或错误的安装配置

一开始，sonarqube服务器由于内存不足问题每月停机两次，我们遵循PRD实例的官方设置文件，尝试在EC2实例上垂直扩展容量，从t2.small扩展到t2.medium，并使用更多内存运行3个java进程：

For Web:
 sonar.web.javaOpts=-Xms256m -Xmx1024m -XX:+HeapDumpOnOutOfMemoryError  

For ElasticSearch: 
 sonar.search.javaOpts=-Xms1024m -Xmx1024m -XX:+HeapDumpOnOutOfMemoryError

For Compute Engine:
 sonar.ce.javaOpts=-Xms256m -Xmx1024m -XX:+HeapDumpOnOutOfMemoryError

但问题仍然存在
