Upgrading from 7.13.7 to 7.18.3

I followed the following guide to update our Confluence: Upgrading Confluence | Confluence Data Center and Server 7.18 | Atlassian Documentation

 

After the install process was finished I went trough the Re-apply any modificiations. Once I was done with these, I started up confluence and waited a good 5 to 8 minutes. I was never able to see the confluence web page as it just spun and spun. I looked at the log and found these in the log:

hello @Clayton Dirkschneider ! Welcome to the Atlassian Community!

The logs seem to indicate you ran out of memory.  You may need to allocate more memory. Here's the knowledgebase article: https://confluence.atlassian.com/confkb/how-to-fix-out-of-memory-errors-by-increasing-available-memory-154071.html

I have checked memory. There is 12GB total and only about 4GB is being used.

What are the  -Xmx and -Xms values?

4Gb may be enough for regular use.  But updating tables on the database as part of the upgrade operation is causing OutOfMemory errors.  You probably have to change the -Xmx and -Xms, even if temporary.

I used the article you had sent over and increased the xmx memory limit and that fixed the issue. Thank you!
