Understanding possible memory leaks

Guidewire applications are memory-intensive. Guidewire applications generally require larger heaps than most other Java applications.

Garbage collection logs might show that memory usage grows significantly over time, resulting in a lack of available memory. Computer science commonly describes this condition as a memory leak. To diagnose the problem, it is necessary to collect a dump of all used objects, called a heap dump, to identify all objects in the heap. Developers familiar with PolicyCenter can then analyze the heap dump. Such analysis helps identify excessive memory usage, identify its root cause and possibly find a change that will avoid such issues.

The investigation of memory leaks differs slightly depending on the JVM platform.
