Cause

Confluence is not able to index some attachments. The files in question may be corrupt or Confluence could be experiencing OOM problems during the indexing task.

Workaround

  1. Disable indexing of attachments following the instructions in How to disable indexing of attachments. That will stop Confluence from indexing the content of the attachments, so the contents will no longer be visible in search. The title of the attachment however will still be indexed and searchable.
  2. After the above is done, Rebuild the Content Indexes from scratch.
