What is error 413?
Clients who post very large Solr queries sometimes see an HTTP Error: The remote server returned an error: (413) FULL head. A similar error, 413 Request Entity Too Large, occurs when indexing very large documents. This means that the Jetty web server used by SearchStax needs to permit larger HTTP headers.
The default Jetty header size is 8 KB, which is adequate for most clients. When larger headers are needed, we raise the limit to 64 KB and have the client try again.
The entire header must be read and processed on every incoming message, so we are reluctant to raise the header size too much. It places a load on the CPU that can negatively impact performance.
Changing the header size requires an adjustment to jetty.xml. Unfortunately, this is not a change that you can make yourself on a cloud server. Contact the SearchStax Support Desk so we can help you.
