Questions to support your analysis include:Ĭan the problem be verified by using another tool, script or metric? The very first step to analyzing an application suspected of having a memory leak is to verify your metrics. Alternatively, there are a handful of dedicated graphical profilers as well as GC-log analyzers available.

Over the years, many approaches and tools have been developed to support memory profiling Java applications use command-line programs such as: jcmd or jmap, which come with the Java Development Kit (JDK). To identify the root cause of a memory issue, developers can use a technique called memory profiling.

So, keep in mind that it is not necessarily your code that is leaking. Additional leaks could be a result of issues within third-party integrations, where other leaks or unsafe calls through the Java Native Interface (JNI) are made and are hard to debug after the fact. Although, there is still a possibility that this first inspection fails, and a hazardous piece of code makes it into the application which may result in high memory usage. These programs can find potential issues such as unclosed streams, infinite loops etc. Popular solutions for this are SonarQube and SpotBugs.

For the sake of early recognition, this analysis should happen at the moment a developer pushes a change to the code repository. To help with this, static code analysis must be executed and provide feedback on which pieces can be improved to prevent bugs or performance problems in the future. When it comes to preventing memory issues, questionable code should not even make it into production. So let’s dive right in! Investigating Java Memory Issues

In this second post we cover more in-depth facets of cloud storage as it pertains to Bitmovin’s encoding service and how to mitigate unnecessary memory loss. 1, we reviewed the basics of Java’s Internals, Java Virtual Machine (JVM), the memory regions found within, garbage collection, and how memory leaks might happen in cloud instances. Welcome back! In our first instalment of the Memory Series – pt.
