Software behavior becomes very difficult to define when a resource (RAM, disk space, etc) is completely exhausted. Even if Lucene's behavior is well defined (which I think it might be -- the index itself is NOT corrupt), Solr is another layer here, and I don't know whether its behavior is well defined. I suspect that it's not. This might explain what you're seeing. That might be the only information you'll get, if there's nothing else in the logs besides the inability to write to the disk.
