Hi,
we get a OutOfMemoryError in RamUsageEstimator and are a little bit
confused about the error.
We are using solr 4.6 and are confused about the Lucene42DocValuesProducer.
We checked current solr code and found that Lucene42NormsFormat will be
returned as NormFormat in Lucene46Codec and so the Lucene42DocValuesProducer
will be returned. Is there any special reason not to have a higher version
of NormsFormat?
This is our StackTrace:
