Diagnosis
The JIRA indexes directory, $JIRA_HOME/caches/indexes, is mounted on a remote network share using NFS.
Cause
The JIRA indexes are created using Java functionality called Lucene. Lucene does not support NFS mounts as stipulated in their IndexWriter docs. This is also listed in our JIRA Supported Platforms.
Solution
Resolution
This can be resolved by moving the indexes directory, $JIRA_HOME/caches/indexes, to a local mount on the server that is running JIRA. This depends upon the OS that is being used - for Windows the Assign a mount point folder path to a drive TechNet article will be of assistance.
