Unable to Start Jira. ERROR: Multiple entries with same key:

[Ajay_Pratap]

I have Jira server deployed onthe local network. because of some power outbreak, Jira stopped unexpetecly. now when I am starting Jira it gives following error:

2018-11-27 18:23:35,332 JIRA-Bootstrap ERROR [c.a.jira.startup.LauncherContextListener] Unable to start JIRA.
java.lang.IllegalArgumentException: Multiple entries with same key: CompatibilityPluginScheduler.JobId.PluginRequestCheckJob-job=Tue No
v 27 12:51:42 IST 2018 and CompatibilityPluginScheduler.JobId.PluginRequestCheckJob-job=Tue Nov 27 18:59:05 IST 2018
at com.google.common.collect.ImmutableMap.checkNoConflict(ImmutableMap.java:150)

I found the following link:

https://confluence.atlassian.com/jirakb/jira-fails-to-start-due-to-multiple-entries-with-same-key-800702874.html

I did the exact steps mentioned but still the issue persists, while jira starts up it gives the fatal error and in database I still can see multiple entries(Even after deleting one according to the above link).

Jira Version : 7.1.9

What exact SQL query did you run to identify the duplicate entries?

Was it

select * from clusteredjob where job_id='CompatibilityPluginScheduler.JobId.PluginRequestCheckJob-job';

?

If not, try running that to see if you have duplicate entries in that table with that job_id value.   If you do, you will need to delete one of these in order to get Jira to start up.

If you have done this and still find Jira is not starting, I'd be interested to check the atlassian-jira.log or the catalina.out file to see what the exact error message is now.  It is possible, although unlikely you might have some other error during startup unrelated to this specific key.
