There was an error during import/export with <unknown plugin>

[Lari Partanen]

Hi Atlassian Community,

Has anyone encountered this error message when exporting an XML backup from a server hosted JIRA? --> "There was an error during import/export with <unknown plugin>:"

Inside the log, it doesn't give a clue on which plug-in could it be, or which jira feature linked to the plug-in encountered the error.

Any clue what other items should i check further? Below is the partial error message from the log.

Error Message:

From the error message it appears that database communication was lost during the xml backup. Here is an Atlassian KB article for MySQL Communication Link Failure. https://confluence.atlassian.com/jirakb/mysql-communication-link-failure-214338032.html
