We performed background indexing but we got the following message from server : JIRA is unable to perform a background re-index at this time because the index files are either missing or corrupted. Although we are able to reach the issue detail directly via issue URLs , we cannot list or seach the issues after this problematic indexing operation. PS. Please keep in the mind that , the last issue we updated before the problematic issue (JCON-80) has a different problems than the others.While we can update other issues, we cannot make any change on this issue now. Now , the system forces to use 'Lock JIRA and rebuild index' but we get the following problem : Indexing completed with 216 errors Task completed in 1 second with unexpected error.
