One page editing problem

[Rafal Rostek]

Hi all.

When we try to edit one page in our confluence intranet we get a timeout.

The server CPU is jumping to 100%. Other pages display and edit without any problems. Only with this one there is a problem.

WARNING [Catalina-utility-4] org.apache.catalina.valves.StuckThreadDetectionValve.notifyStuckThreadCompleted Thread [http-nio-20001-exec-42] (id=[36352]) was previously reported to be stuck but has completed. It was active for approximately [166,750] milliseconds

How can I fix it?

Regards

Hi @Rafal Rostek ,

Thank you for sharing the requested logs. 

Looking at the Catalina logs, I could see about 8 stuck threads for page edit action for page id - 66521372. 

Looking at the errors, it seems the content reconciliation cannot be executed. This is one of the tasks that synchronize data between the Confluence tables (CONTENT and BODYCONTENT) and the Synchrony tables (EVENTS and SNAPSHOTS). This is needed because Confluence and Synchrony keep copies of the content independently.

We have a matching KB for this issue and the symptoms match the one mentioned in the KB - Editing and creating pages on Confluence fails. Timeout messages appear in the UI, especially while trying to publish changes.

• Editing and creating pages fails on Confluence due to content reconciliation errors

Kindly follow the steps listed under the above KB and I hope this fixes the issue for you.

Thanks,

Aamir

Hi @Rafal Rostek,

Thank you for reaching out to Atlassian Community.

Can you please attach the full catalina.out logs to look for stuck threads? It seems the page is using some macro that is causing the issue. The stack trace will help us to identify the issue.

Thanks,

Aamir

Also the Confluence application log (ideally just the bits around where you started the edit and where the CPU dropped back down)

[Rafal Rostek]

They were set while trying to edit the page:

tail -f /opt/var/atlassian/application-data/confluence/logs/atlassian-confluence.log >> /home/rrostek/atlassian-confluence.log

atlassian-confluence.log 

tail -f catalina.out >> /home/rrostek/catalina.out
