This looks like your request POST is 6 megabytes in size, which is larger than the default 2MB limit. Toke has mentioned maxPostSize in the Tomcat configuration, but I don't think that will do it. SOLR-4265 (available as of Solr 4.1), in addition to letting Solr enforce UTF-8 encoding regardless of the container config, also programmatically sets the maximum POST size from solrconfig.xml, defaulting to 2MB, and probably overriding any container-level config like maxPostSize. You can change this value in solrconfig.xml by adding/modifying the formdataUploadLimitInKB attribute on the requestParsers tag. The HTTP error code also supports my conclusion -- 4xx response codes usually indicate a problem with the request, whereas 5xx response codes indicate a problem with the server. I suppose it's possible that the size limitation might also apply to the response, but that doesn't feel right to me. Thanks, Shawn
