JIRA Server Troubleshooting

by László L. Lieszkovszky

Logs to check (installed on Ubuntu):

  • /opt/atlassian/jira/logs/catalina.out
  • /var/atlassian/application-data/jira/log/atlassian-jira.log

Look for any "error"-s in the above files.

If there's nothing, perhaps the kernel is killing off the Java process. Check:

  • /var/log/syslog

Example of the above:

As you can see, ClamAV virus db update/scan resulted in OOM so the kernel killed off the Java process.
