Collaborative Editing stopping Confluence Editor

[Gerhard Hannemann]

Hi

Have a Standalone Confluence Server (licensed for maximum ten users), installed on CentOS7.  This system uses Open JDK 11 (JRE headless), Postgresql and Confluence 7.4.6 - Server version.  There is only one instance of this server.

It is also blocked from access the internet.  The Base URL matches an entries on the local host file and internal DNS.

I reported in a previous question that the Confluence Editor would not load and it was running extraordinarily slow.

Digging around the logs and configuration, I found that the behavior appears to be associated with collaborative editing, specially synchrony.

As soon as I turn collaborative to OFF (or even Limited), the editor comes to life and confluence becomes much more responsive.

I have not fiddle with the reveres proxy or outbound proxy settings at all.  I have a similar setup running Debian and internet access is allowed.  I have no issue with he latter setup.

I also had quick look at the synchrony troubleshoot guide - not much of this matches our  simple standalone setup.

What could be causing this?

Regards

Gerhard

Gerhard,

  I would check server resources first.  If everything is properly sized and you have enough memory for collaboration to work properly then it is most likely a routing issue.  I have had lots of issues with collaborative editing working on servers with proxy and it is always challenging and time consuming to get it to work.  Synchrony runs on port 8091 by default, and an internal Synchrony proxy runs when collaborative editing is turned on.  This is a great place to start in the reverse proxy section - https://confluence.atlassian.com/doc/troubleshooting-collaborative-editing-858772087.html
