Synchrony process won't start either with Confluence or manually.

The following error appears in the atlassian-confluence.log

ERROR [Long running task: Restart Synchrony Task] [plugins.synchrony.tasks.AbstractConfigLongRunningTask] runInternal An error occurred when running a Synchrony ConfigLongRunningTask
 -- url: /rest/synchrony-interop/restart | referer: | traceId: 4e06227767fccf2b | userName: XXXXX
java.lang.NumberFormatException: For input string: ""


Synchrony PID file has been corrupted.


The PID file is created when starting Confluence, in case it doesn't already exist. The steps below will fix the issue:

  1. Stop Confluence 

  2. Remove the file <confluence-install>/temp/

  3. Start Confluence

DescriptionSpecific error message appears in the logs when attempting to start synchrony
