Can't view particular Excel attachment: java.lang.OutOfMemoryError.

When we try to view an Excel attachment, it gives this stack trace. The Excel file is large, is 498kb, with name new_cols_treq_2004990.xlsx. When clicking View on the Attached Files page, it gives this stack trace. The View link is

https://cms.prod.xxxxxxxxx.com/team/pages/worddav/preview.action?fileName=new_cols_treq_2004990.xlsx&pageId=21204522

The version of Office Connector is 1.18, the latest version compatible with our Confluence 3.4.8.

We would like it to present a user friendly error message instead of a stack trace. Maybe something along the lines of The attachment is too big to view.

Sometimes the error is simply: Error formatting macro: viewfile: java.lang.OutOfMemoryError: Java heap space

Here is the stack trace:

Just to echo Harry's comments above. We have a document that is designed to walk you though the steps to allocate more memory to your heap.

https://confluence.atlassian.com/display/CONFKB/Out+of+Memory+Heap+Space

Also to clarify, you are not trying to render the document in the page. You are seeing this error just when a user clicks on the attachment to download it?

It is when trying to render in the page, using the Office Connector. The problem was the Office Connector is bad. There were many columns and Office Connector does not handle them well. We deleted the extra columns and it worked.

Hi, the out of memory exception has to do with your server not having enough memory to do this operation. Can you post the memory allocations for Confluence? You'll need to increase memory to fix this.

The server has 24GB and Tomcat is allocated 8GB. Should be plenty.
