We are facing this issue for long and we can't afford this frequent crashes in the production environment. We have used high-end EC2 Instances to process the heavy workload. This type of error only occur under the heavy workload, otherwise, it works fine.

I have also checked MongoDB CPU, RAM and query load during the crash but everything was normal at that time. The only which we have faced was in node server which was restarted with below error of MongoDB.

Instance 1: Node Server 

• c5.4xlarge: 16 CPU and 32 GB RAM with SSD storage
• Node version: 6.11
• MongoDB NPM Version: 1.4.28
• CPU Utilization is 30-40 % in normal condition with 8 Socket servers
• CPU Utilization is 70-80 % during the crash with 8 Socket servers

Instance 2: Standalone MongoDB Server

• r4.2xlarge: 8 CPU and 61 GB RAM with SSD storage
• MongoDB Version: 3.2.20
• CPU Utilization average 300% out of 800% and remain the same during crash also.

Error logs from node socket server:
