Hi,
We are using 3 node SOLR (7.0.1) cloud setup 1 node zookeeper ensemble.
Each system has 16CPUs, 90GB RAM (14GB HEAP), 130 cores (3 replicas NRT)
with index size ranging from 700MB to 20GB.
autoCommit - 10 minutes once
softCommit - 30 Sec Once
We are facing the following problems in recent times
============================================================================================
1. Few Indexes goes to recovery mode without any prior error or warnings

How can we fix "AlreadyClosedException" without restarting the service.
Thanks,
Doss.
