Description

This issue is related to https://issues.apache.org/jira/browse/SOLR-5214. Although memory issues due to merging have been resolved, we still run out of memory when splitting a shard containing a large segment (created by optimizing). The Lucene MultiPassIndexSplitter is able to split the index without error.
