Hello, I have a solrcloud setup on Windows server with below config: 3 nodes, 24 shards with replication factor 2 Each node hosts 16 cores.
Index size is 1.4 TB per node Xms 8 GB , Xmx 24 GB Directory factory used is SimpleFSDirectoryFactory The cloud is all nice and green for the most part. Only when we start indexing, within a few seconds, I start seeing Read timeouts and socket write errors and replica recoveries thereafter. We are indexing in 2 parallel threads in batches of 50 docs per update request. After examining the thread dump, I see segment merges happening. My understanding is that this is the cause, and the timeouts and recoveries are the symptoms. Is my understanding correct? If yes, what steps could I take to help the situation. I do see that the difference between "Num Docs" and "Max Docs" is about 20%. Would appreciate your help. Thanks, Rahul
