I seem to be getting a very similar issue to
We have a parent issue 'Site' which has many linked issues 'Investigations'
The site WF has two main statuses 'No Investigation' and 'Investigation Open'. Whenever a linked investigation is opened the linked Site is changed from 'No Investigation' to 'Investigation Open'. Each time an Investigation is closed it changes (or tried to change) the status of the site to 'Investigation Closed' the site has a WF condition validator making sure all linked issues are closed before it will transition.
Now when ever we try to transition a investigation to closed and the linked site has other investigations that are still open it failes with that transaction error.
This was all working fine in jira 6.3.x. We transitioned to Jira 7.1.4 last night and now its broken the workflows using these delayed writes. Running 2.2.9 (i have also tried 2.2.8).
Can you please help!
I have attached some pictures to help.
