Description Werner Van Belle 2017-04-29 15:58:00 CEST 
This bug happened after clearing all the caches and trying to load the nearest neighbors.

It might have to do with the fact that I removed synchronisation data from a certain host.

Or it might have to do with the shouldYield method we added ?

It might have to do with the ReadWrite lock we implemented.

Directly afterwards, the database was apparently intact.
