The log indeed shows that the database was recovered from an unexpected shutdown. Unfortunately it seems that one of the indexes (ObjectNode.modified) became non synchronized with the data or corrupted. This shouldn't happen of course as recovery from failure should protect data and indexes, so we will have to investigate this further.

As a quick solution, you may try to remove the index, i.e. access the database with a class (in the classpath)  in which that index is not defined, and then again redefine the index by accessing the database with a class (in the classpath) in which that index is defined.

Alternatively you should be able to repair the entire database by running the Doctor.

We will also check why you got the error in submitting the ticket.
