Hi Eric No its not NFS. It is ext4.
Our solr is going again and again into OOM error. I am really not sure will it be because of this exception. But what I observed was Whenever we will increase polling interval, heap memory will grow at slower rate as compared to lesser polling interval. But we were not able to reproduce the same error on solr 6.2.0. And what I noticed from logs was every time IndeXfetcher gets called CachingDirectoryFactory was opening the core in 6.2 but the same doesnt happen in 6.1.0 Verion Let me know if there is something else to this issue as Our chances of upgrading the same are very less till we are sure its not any configuration issue. -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
