Yes, it means your upgrade has failed and you need to revert to the backup you took before you ran the upgrade.

Preserve the log files before you roll back - you will want to read them to find out why the upgrade failed.

In which Directory will I find the respective log file?

Unless you have reconfigured it, you will find it under the "home directory" you set for confluence, beneath /logs Should be called atlassian-confluence.log

I can find these SEVERE errors in a log-file: wrong JDBC-Driver? SEVERE: The web application [] registered the JDBC driver [org.hsqldb.jdbc.JDBCDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

To prevent a memory leak, the JDBC Driver has been forcibly unregistered. Feb 26, 2015 4:19:44 PM org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc SEVERE: The web application [] registered the JDBC driver [net.sourceforge.jtds.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered. Feb 26, 2015 4:19:44 PM org.apache.catalina.loader.WebappClassLoader clearReferencesThreads SEVERE: The web application [] appears to have started a thread named [Statistics Thread-__DEFAULT__-1] but has failed to stop it. This is very likely to create a memory leak.

Hmm, well, that is a problem, but it's an issue as the server is shutting down - you need to concentrate on the upgrade errors.

Hi Johannes,

The Atlassian-confluence.log files should have a more detailed information on the upgrade failure. If you are unable to pinpoint the reason why the upgrade failed in the logs, I suggest to get in touch with the Atlassian support so we can investigate the root cause.

Cheers,

Rodrigo
