[Carsten Grzemba]

I upgraded confluence from 6.15.4 to 7.4.3. After that I can't start or enable Collaborative Editing

In the attlassian-confluence.log:

Hello @Carsten Grzemba !

Looking at the error you posted here:

2020-09-03 14:59:46,936 ERROR [Long running task: EnableTask] [confluence.util.longrunning.ConfluenceAbstractLongRunningTask] run Long running task "EnableTask" failed to run.

I believe that you are affected by the situation described here:

• [Confluence Server] Synchrony startup fails with "Failed to get mem_unit from sysinfo" error

You can check the the workaround at the end of the Knowledge Base page. I do recommend that you read the entire page for a better understanding of the issue.

Let us hear from you!
