Hello *, We are using SolrClould 4.0 - Alpha and have a 4 machine setup.
Machine 1 - 16 Solr cores - Shard 1 - 16 Machine 2 - 16 Solr cores - Shard 17 - 32 Machine 3 - 16 Solr cores - Replica 1 - 16 Machine 4 - 16 Solr cores - Replice 17 - 32 Index at 500 docs/sec and committing every 60 seconds, i.e., 30,000 Documents causes Solr to freeze. There is nothing in the logs to indicate errors or replication activity - Solr just appeared to freeze. Increasing the commit frequency we observed that commits of at most 2,500 docs worked fine. Are we using SolrCloud and replications incorrectly? -- Raghav
