Confluence performance issue, stack trace

Question

Hi all,

We are running a Confluence server on premise, version 5.8.5. Response times, from login to browsing, are very long. Moreover, confluence-server.log contains a lot of occurences of this message:

Required plugin module com.atlassian.plugins.atlassian-nav-links-plugin:rotp-menu was either missing or disabled

Our Confluence is running on Java 1.8.0_45, with an Apache Tomcat 8.0.23, which seems to be compatible if I'm not wrong.

Would anyone have a clue on the possible cause of this problem?

Thanks a lot,

Fred

Hi Frederic,

Maybe the plugin is corrupted? Could you try to re-install that?

Also we had some issues with JAVA 1.8.0_45 and Cofluence 5.8 over SSL as you can see here:

https://jira.atlassian.com/browse/CONF-37909

It was fixed Confluence 5.8.8. I know it isn't the same issue, might be related.

Regards,

Renato Rudnicki

Hi Luiz,

Thank you for replying!

I checked the system plugins upon your remark, and saw that the NavLinks plugin was not enabled. So, I clicked the "enable" button, but it is failling, and in the Confluence server log I see the following error:

2015-08-27 17:18:49,392 ERROR [http-bio-8443-exec-7] [atlassian.plugin.manager.DefaultPluginManager] enableConfiguredPluginModule There was an error loading the descriptor 'null' of plugin 'com.atlassian.plugins.atlassian-nav-links-plugin'. Disabling.

Talking about memory or other perfomance tuning tips, everything seem all good (plenty of memory available, ...).

I am wondering if this is not a JDK version problem, or something like this...

Thanks,

F.
