Out of Memory Java Heap Space Error 2018-05-11T14:19:53+00:00

Out of Memory Java Heap Space Error

CopyStorm uses the default settings for Java heap space. Most of the times this works well, but if you are seeing an Out of Memory error referencing Java Heap Space you may need to increase the memory allowance for CopyStorm. Settings can be adjusted as described in the “CopyStorm.bat” file, but the exact settings will depend on the size needed for the data in your Salesforce instance.

The most common reason to adjust the default memory settings is that a large content item (usually an Attachment, Document, or ContentVersion) is too large to fit in available CopyStorm memory. CopyStorm requires 3 to 4 times the size of the largest content item. Here are the steps to find the largest content items in your Salesforce:

In the management menu found by clicking on your name in the upper right-hand corner, go to:

Setup -> Data Management -> Storage Usage -> Overall Top Files by Storage Utilization
