A problem similar to JRASERVER-68477.
Method JiraDashboardStateStoreManager after updating/deleting Dashboards on Jira Data Center, allocation the entry in the 'clusterlockstatus' table remains left behind. The 'locked_by_node' for that row will be empty, but they pile up in large numbers.
- Run Jira DC
- Update/Delete Dashboard
Once the operation is done, the entry in the 'clusterlockstatus' should be removed.
'lock_name' entries like "com.atlassian.jira.dashboard.JiraDashboardStateStoreManager.dashboard-69114" pile up in the 'clusterlockstatus' table.
One customer had over 7000 of them.
If necessary, delete the unnecessary 'lock_name' entries manually.
