Hi Lan,

You need to increase the memory allocated to the Maximum Heap memory pool of your JVM, (-Xmx), as described in this document, (which works the same for both JIRA and Confluence): https://confluence.atlassian.com/display/JIRA/Increasing+JIRA+Memory

If you have any problems, please open a ticket with Support and we can advise you further on your configuration to prevent these problems.

All the best,
John

Hi, if you are trying to do an XML backup on a large instance, lots of memory may be required. I'd suggest backing up the database and the home directory instead of doing an XML backup in this case. This will prevent those out of memory errors.
