The error message you showed here does not list the cause. Is there more to the error message, one or more "Caused by" sections? Please include the entire stacktrace. I would be surprised if there's not more on the client side, but even if there's not, Solr's server-side log should contain more information. Looking ahead to your other reply on this thread, it's a bad idea to do a commit after every document, unless the update batch only consists of one document and there will be a long delay before another document gets added. The autoCommit and autoSoftCommit features are good options. Do the autoCommit with openSearcher=false. You can also do a "commitWithin" parameter on the update requests instead of autoSoftCommit. You should always have autoCommit with Solr 4.x, to ensure the transaction log does not grow out of control. Thanks, Shawn
