There's pretty much zero information to go on here. I would suspect performance problems leading to zookeeper client timeouts, which will cause Solr to think servers are down when they're not. The most likely causes for performance issues (aside from simply trying to make too many queries or simultaneous update requests) are: * A java heap that's too small. * A java heap that's very large, without proper GC tuning. * Not enough RAM for the index size. The apache wiki server is down at the moment, so this URL will not work at the time I am writing. When it works, it contains a larger description of the problems mentioned above, and a few other ideas: http://wiki.apache.org/solr/SolrPerformanceProblems You can visit the google cache for that page, which I believe is completely up to date: http://webcache.googleusercontent.com/search?q=cache:dv-tzFUweQ8J:https://wiki.apache.org/solr/SolrPerformanceProblems+&cd=1&hl=en&ct=clnk Thanks, Shawn
