java.lang.String#intern() is an interesting function in Java. When used at the right place, it has potential to reduce overall memory consumption of your application by eliminating duplicate strings in your application. To learn how intern() function works, you may refer to this blog. In this post let’s discuss the performance impact of using java.lang.String#intern() function in your application.

Recently we confronted an interesting ‘java.lang.OutOfMemoryError: Metaspace’ problem in a Microservice application. This Microservice application will run smoothly for initial few hours, later it will start to throw java.lang.OutOfMemoryError: Metaspace. In this post let me share the steps we pursued to troubleshoot this problem.

The application that we are going to discuss in this post was running on Elastic Beanstalk (EBS) service in Amazon Web Services (AWS). Intermittently this application was throwing HTTP 502 Bad Gateway error. In this post, let’s discuss how we troubleshooted and resolved this HTTP 502 bad gateway error in Elastic Beanstalk service.
