as I said before. we also come across the issue. and I just guess the possible reason. let's wait the expert to explain for us. on the other hand. I find that your index data is 68G, that is too large, I recommend you to use solrcloud, as the guide reference, the reasonable size is around 15G. now our project use solr and solrcloud together so that if anyone down or other issue, we can switch to the well-running one.
