Upgraded from 5.7.4 to 6.9.1 and it just hangs.

[Flatirons Project]

After doing an upgrade  from 5.7.4 to 6.9.1 using the embedded database, confluence never gets to the login page.  It just hangs at a blank site.  I am using the <localhost-ip>:8090

Looking through the logs I am not seeing anything that gives me the idea of an error.  Any help is appreciated.

Thanks

Robert

Hi - The error that stands out for me in your logs is: 

Connections could not be acquired from the underlying database!

Please check out the causes and resolutions on Connections could not be acquired from the underlying database  to see if any of them apply in your case.

Thanks,

Ann

Thanks Ann,

This is where I am confused.  I am using the embedded database and everything was working in 5.7.4.  All I did was run the installer for 6.9.1.  Atlassian's upgrade path said I should be able to do 5.x - 6.x with no issues.  I guess I am going to have to restore the snapshot and do incremental backups until I figure out what breaks.

5.7.4 to 5.10.9 works with no issues.

[AnnWorley]

Hi - Thanks for the GC logs. For more basic error messages please check:
* <confluence_install>/logs/ (anything recent in this directory)
* <confluence_home>/logs/atlassian-confluence.log
(note) The <confluence_home> directory is the path defined in the following file: <confluence_install>/confluence/WEB-INF/classes/confluence-init.properties

If you see any errors in the atlassian-confluence.log, especially between the phrase "Starting Confluence" and "Confluence is ready to serve" please post them so we can investigate.

Thanks,

Ann

The log should be telling us something, I'm afraid you're going to need to share them and look for errors in them.

There's one exception, where Confluence is running fine, but you're looking in the wrong place for it - that will not show in the log.  Check your server.xml file - does it have a "context" set in it?  If it is set to "", then we need to start looking at logs, but if it is set to something like "/confluence" or "/docs", then look there instead - try <localhost-ip>:8090/confluence or whatever you have in the context path.

Here is my server.xml.  This system was built with a fresh 5.7.4 confluence with the embedded database since it is only a 10 user system.  I created an account and added some content and then ran the .bin 6.9.1 installer.  This is running on CentOS 7.5 if that helps any.
