Wiki import taking forever (weeks)!

[Joe Reyna]

I setup a brand spankin' new confluence 3.5 wiki and tried doing an import of a 3.1 confluence wiki, but it wanted to take weeks for it to complete. I then tried it without attachments and the same thing occurred. Progress never passes 1%. I don't see anything helpful in the confluence logs.

My setup is using an external pgsql 9.0 database which connected fine in the initial setup.

My ultimate goal is to do a 3.1 -> 3.5 -> 4.3 upgrade.

Perhaps you need to increase the memory vor the JVM? Try setting it to 1G at first. Of course the proper size of memory depends on the size of the backup...

The backup is only 153MB. I'll check virtual memory. Thanks!

This fixed the problem. Once I increased the java memory in /usr/local/confluence/bin/setenv.sh it worked and my import completed in 3 hours as opposed to several weeks. Thanks!!

Any specific reason why you are doing an import rather than upgrading it manually? As a quick workaround, I would recommend you to upgrade Confluence manually rather than using XML site backup/restore.

• Upgrading to Confluence 3.5.x
• Upgrading to Confluence 4.3.x

If this still fails, please raise a new support ticket through https://support.atlassian.com

I didn't want to mess with the production server so I was doing this in a testing environment. Are you saying I should import to 3.1 first and then go to 3.5 and then 4.3.x?

Hey Joe,

Have you looked in the atlassian-confluence.log file from the confluence-home/logs to see what is happening at this point? Maybe the import is crashing for some reason?

Cheers,
Boris

There is nothing unusual going on in the logs...

I did find java heap out of memory errors in the catalina.out log.
