Thanks Uwe, yes it is on 32 bit in extremely tight memory situation. I just was curious what the reason is (on bigger machine it works). Lucene core requires more real memory? Can you please a bit elaborate, can I estimate it somehow? I do not remember seeing any changes that would cause core to use more memory (we do not sort, no norms overall... this failed just on opening IndexReader)...
