If JIRA is stopped whilst Lucene is reindexing itself, it may leave a lock file behind. This will cause issue indexing to fail on subsequent startups and they will get errors like

Caused by: java.io.IOException: Lock obtain timed out: Lock@/usr/prod/jira/atlassian-jira-enterprise-3.4.3-standalone/temp/lucene-9683c976083ae985fecc9c87bdbac47b-commit.lock
	 at org.apache.lucene.store.Lock.obtain(Lock.java:58)
	 at org.apache.lucene.store.Lock$With.run(Lock.java:108)
	 at org.apache.lucene.index.IndexReader.open(IndexReader.java:111)
	 at org.apache.lucene.index.IndexReader.open(IndexReader.java:95)
	 at com.atlassian.jira.util.LuceneUtils.getIndexReader(LuceneUtils.java:31)

The solution is for the user to stop JIRA, and remove the file before starting JIRA again.

We should add a Johnson Filter to run this check at startup and give them the appropriate instructions / warning if this occurred.

Can you explain how to clear these locks once they're there?

Which file, and where is it located?

Susan,

The IOException in the JIRA log will indicate the location of the lock file. For example:

Caused by: java.io.IOException: Lock obtain timed out: Lock@/usr/prod/jira/atlassian-jira-enterprise-3.4.3-standalone/temp/lucene-9683c976083ae985fecc9c87bdbac47b-commit.lock

The lock file is located in the /usr/prod/jira/atlassian-jira-enterprise-3.4.3-standalone/temp/ directory.

Cheers,
Donna
