Forum OpenACS Q&A: Aolserver crash, indexing with OpenFTS

I am experimenting with OpenFTS to index german language documents. Therefor i set openfts to use a german language ispell dictionary (1,2MB), affix file and stopwords file. In addition the "UnknownDict" is registered.

Unfortunately aolserver crashes sometimes after indexing a large number of documents (500+) with "No memory for AddSpell". Does OpenFTS load the whole dictionary for every single index run on a document? What could be the problem here?

TIA, peter
