Problem
When exporting a space to HTML, the resulting files are blank or do not contain most of the content.
The following appears in the atlassian-confluence.log file:
INFO: More than the maximum number of request parameters (GET plus POST) for a single request
([10,000]) were detected. Any parameters beyond this limit have been ignored. To change this limit,
set the maxParameterCount attribute on the Connector.Cause
For large spaces, the export action violates the default maxParameterCount in the Tomcat connector.
Resolution
Include the parameter in the Tomcat connector by editing the server.xml in your <atlassian-installation/conf/> directory. In a default connector, it would look like the following example:
<Connector port="8090" connectionTimeout="20000" redirectPort="8443" maxParameterCount="20000"
maxThreads="200" minSpareThreads="10"
enableLookups="false" acceptCount="10" debug="0" URIEncoding="UTF-8"
protocol="org.apache.coyote.http11.Http11NioProtocol" />Since the default value is 10000, you may tweak the setting in increments until resolution.
