Recently, it has come to our attention, there were performance issues related to BigPicture in JIRA Data Center caused by improper cluster node deactivation within BigPicture.
The issue manifests itself only when you update BigPicture multiple times without restarting JIRA. It results in multiple orphaned BigPicture server runnings on a single JIRA cluster node, causing the performance issues.
The issue had been resolved and the fix was implemented on 2017-07-31. It requires a user to restart their JIRA environment after the upgrade in order to terminate all mentioned ghost servers.
Restart the JIRA environment after the plugin upgrade. Please make sure BigPicture has properly initialized its cluster (check for log entries as shown below)
