When trying to to a full text index on a collection of texts, the process runs for a couple of hours with the exit message below - I think it is near completed. From the GUI, I have at least seen the progress bar get to around 80 %, so I think it is safe to assume that the error is connectedt the final stages. 

The texts are unstructured and represented as one line pr. book. Here is the result from the index process. Parameters set in GUI are: Norwegian Snowball, lemmatization, diacritics. There is set aside 30GB for the GUI.

Path summary:

Here is the error message:
