I recently upgraded jira from 7.5 to 8.5.7 in an hope that newer version might solve issue like occasional shutting down issue which happens about once a day.
However this upgrade only made things worse as it happens more than 5 times a day!!
Bellow is on of the logs I found in the /opt/atlassian/jira/logs folder.
