Hi Erick,

Thanks for response. I created a java heap dump of the server after the exception throw. It's
a bit big. I uploaded it to my baidu cloud. You can download it by clicking below link:

> So, I thought it's probably not a memory issue. By the way, I have a solr 5.3 server
with the same amount of documents (2506889) in a one shard core which does not have this exception.
