Mysterious runtime errors in logs (with influence on the performance)

[Manuel Kummerländer]

Hi,

we noticed the following strange behaviour on our instance:

One user copied pages some days ago. Today he just opened one of this pages, no editing or other changes. Since he opened the page our log gets thousands of these errors:

2015-05-18 10:19:16,540 ERROR [AtlassianEvent::CustomizableThreadFactory-6] [confluence.mail.notification.DefaultNotificationsSender] sendNotification Error sending notification

The performance of our instance went down since then. We restartet the system and now everything is fine, but how long? We have no idea what caused these errors and how to prevent them ...

Has anyone here? Thanks!

Regards
Manuel

This appears to be a problem with database storage which was depcrecated in Confluence 5.5 which means it will not be fixed. Can you verify that this is the issue that is affecting you?
