Hi Christoph,

while it is quite hard to pinpoint it from just having the log file snippet here - one question: did this happen also on a foreground Re-Index?

Second question would be if the Re-Index ran basically through despite one NPE or if this is a broader show stopper.

From our experience the one or another outdated App might be causing this - so it's a good idea to check them through UPM for potential updates. This is just educated guess, though as there might be several reasons for the NPE you got in logfile.

Cheers,
Daniel
