Question

我有一台开发机器，它在Amazon EC2上运行，主要是从使用MobaXTerm的Windows计算机访问的。主要用途是启动和使用Jetbrains PHPStorm，这是一个基于Java的IDE。

我经常遇到IDE锁定。当发生这种情况时会发生一系列奇怪的事情：

在MobaXterm中命令行上的其他ssh连接到同一台机器工作，直到我输入＆＃34; ps -ef＆＃34;并显示PHPStorm的行：

D重新启动EC2实例似乎不再起作用了

E停止实例需要很长时间，根据我的经验表明缺少RAM。不过我已尝试使用16GB和32GB机器，并且还增加了2GB的交换空间。这比我的其他桌面开发机器要大得多，PhpStorm永远不会冻结。

操作系统是Ubuntu 16.04，它是完全最新的。

在亚马逊控制面板上，我检查了所有EC2指标，并且唯一具有任何测量值的是网络输入和输出：

我还检查了附加的单个EBS磁盘50GB的指标，如下所示：

最高指标是66.6KBytes VolumeWriteBytes，远低于50GB卷的150 IOPS / 2400Kb / s的规定性能
