High memory utilisation in Backoffice.

[Huskar]

Hi Experts. We are on Hybris 2011 and things are working fine until we open backoffice. Before opening backoffice, HAC shows used memory around 2GB but after opening backoffice, it goes up till 6GB. Any idea where can be this issue, is there any memory leak or something.

Thanks for quick response. We are already on 2011.15. But there are some of our custom extension which are not on latest version. Can it be a reason. If yes how to debug the culprit code?

It depends on what you customized it actually. To understand that your customizations are the main cause, try commenting out your extensions from localextensions.xml and try to reproduce the issue. If it still goes up to 6GB, then your custom code may not be the main reason.

If the issue is easily reproducible on local environment, I suggest you to use memory profiling tools (e.g. VisualVM) to understand what causes high memory usage. It will not tell you the exact location of the problem, but it may guide you about the possible cause.
