Heap Memory Error Tomcat

Out Of Memory Errors, or OOMEs, are one of the most common problems faced by Apache Tomcat users. Generally, these errors occur during development, but can even occur on production servers that are experiencing an unusually high spike of traffic.

seemingly hard to fix, and show you how organizations using Apache Tomcat in enterprise production environments use Tcat to fix and avoid these errors. What Causes An OOME? The literal cause of an Out Of Memory apache tomcat out of memory error Error is simple: a given Tomcat instance uses up all of the heap memory allocated to it, causing an application or server crash. Thus, the errors themselves are not particularly puzzling. The reason why OOMEs have become such a persistent topic of discussion in the Apache Tomcat community is that they are difficult to trace to their root cause. A stack trace will not show the cause, as the problem usually lies increase tomcat memory windows not with Tomcat, but the web application. Meanwhile, the 'incorrect' web app code causing Tomcat to run out of memory is usually technically correct. That is to say, in any context other than a container managed environment, the code would be considered standard. It is easy to see why a developer might have trouble determining which 'correct' section of their code was incorrect. Here are some of the most common root causes of an OOME: a simple case of the heap size being too small running out of file descriptors more open threads than the host OS allows code with high amounts of recursion code that loads a very large file into memory code that retaining references to objects or classloaders a large number of web apps and a small PermGen Fixing Out Of Memory Errors If you are encountering Out Of Memory Errors, the first step is to determine exactly where the error is coming from. Sometimes, the fix is as simple as increasing the starting heap size or PermGen. For more information on how to configure these options, visit our guides to Tomcat Performance Tuning and Tomcat JVM Configuration. In other cases, fixing an OOME will require you to refactor some of your code to make it suitable for a container-managed environment. Below, you'll find so
