問題

At random occurrences, customer notifications may fail to be sent with the following error appearing in the atlassian-jira.log:

診断

The customer is not using the latest version of the 3rd party add-on Insight - Asset Management for JIRA.

原因

The root cause is unknown and is still being investigated.

ソリューション

Upgrade this add-on to the latest version. If that still doesn't resolve the issue, raise an issue to Atlassian Support.
