I have a system that has been running for a few months now. We have noticed recently that the heap size is growing and is now exceeded the available space. Total Memory 2GB Non-Heap 320MB Heap 1.9GB Version 8.1.12 There are no timed gateway scripts. As this is using the embedded JAVA packaged within the Ignition install. Is there a way I can obtain a dump of the heap to start to identify the root cause of this leak? I can try increasing the heap size when I can next shutdown the system, However it looks to be growing over time so an increase in total memory only delays the issue. I would really like to know how to identify and resolve the root cause. ---

Install any JDK with the same version as the embedded java. That will give you the tools you need, like `jhat`. You will almost certainly want to compare a nearly clean system (post restart) against the situation when nearly full.
