Browser throws 'Out of Memory' exception while loading Jaspersoft Reports

Products

• Clarity PPM On Premise
• Clarity PPM SaaS

Issue/Introduction

• Multiple tabs are opened in a web browser
• Large Jaspersoft reports are loaded in each of them
• At some point during the loading process, the page displays 'Out of Memory'
• All other pages that were loading Jaspersoft reports also display the same message
• A spike in CPU and RAM usage is noticed via the Task Manager on the PC
• No related messages are noticed in the jasperserver.log or the catalina.log, on the server side

Environment

• Jaspersoft 8.1.1

Resolution

• This would be due to a crunch in resources on the client side
• The same reports that were attempted to be loaded directly via the web browser, can be executed by scheduling them instead. If these schedules deliver the reports, then that provides a confirmation that the issue is on the client side, in the PC that is being used.
