Best practices to reduce the memory that is used by a single Html Dialog?

SupportIvyTeam — Mon, 20 Nov 2017 07:54:54 -0500

We have a huge Html Dialog that uses around 80 MB memory per session on the engine side. The dialog is like a wrapper for the full application. It contains multiple tabs and modal dialogs <p:dialog />.

Why is this Dialog consuming so much memory? Are there any best practices to build lightweight JSF dialogs?

Can I reduce the session-views that are held in the engine memory?

The Axon.ivy ivy Engine caches 20 JSF Dialog views per session. As I have a huge dialog with lots of sub-Dialogs this consuming a lot of memory on the Engine. Can I somehow reduce the amount of cached views?

After uploading files we get an OutOfMemoryError: Java heap space

We use a the p:fileUpload widget form primefaces with an upload listener like this:

<p:fileUpload fileUploadListener="#{logic.uploadFile}

In the listener method we copy the file content to an byte array on a data class to store it later. The script looks like this:

byte[] content = IOUtils.toByteArray(in.fileUploadEvent.getFile().getInputstream());

But after uploading multiple files we get an OutOfMemoryError: Java heap space
