Incessant indexing error (Unterminated string at character)

[linzhixnig]

I got the following errors repeatedly and incessantly in catalina.out.

…

I suppose it might be caused by kind of indexing errors.
Especially, the message like "Requested format at index 56, but it wasn't found" can be an Apache POI error of a MS file format.

How can I fix it?

Hi

This looks like a JSON encoding error (and may have been fixed).
Can you turn on the SOLR debugging as described on the wiki and find the node that is causing the problem
Then find the node in the node browser and post the meta-data.
Then there is enough to check if this is still an issue.
