我们长期面临这个问题，在生产中无法承受此类崩溃。我们已经使用高端EC2实例来处理繁重的工作量。此类错误仅在工作量很大的情况下才会发生，否则，它将正常工作。
在崩溃期间，我还检查了MongoDB的CPU，RAM和查询负载，但当时一切正常。我们面临的唯一问题是节点服务器，该服务器由于MongoDB的以下错误而重新启动。
实例1：节点服务器
c5.4xlarge：具有SSD存储的16个CPU和32 GB RAM
节点版本：6.11
MongoDB NPM版本：1.4.28
在8个Socket服务器的正常情况下，CPU利用率为30-40％
在8台Socket服务器崩溃的情况下，CPU利用率为70-80％
实例2：独立的MongoDB服务器
r4.2xlarge：具有SSD存储的8个CPU和61 GB RAM
MongoDB版本：3.2.20
CPU利用率平均为800％中的300％，在此期间保持不变 也会崩溃。
