There is an error in the XML document. The maximum nametable character count quota (16384) has been exceeded while reading XML data. The nametable is a data structure used to store strings encountered during XML processing - long XML documents with non-repeating element names, attribute names and attribute values may trigger this quota. This quota may be increased by changing the MaxNameTableCharCount property on the XmlDictionaryReaderQuotas object used when creating the XML reader. The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:00: '. The maximum array length quota (16384) has been exceeded while reading XMLXML data. This quota may be increased by changing the MaxArrayLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'SubmitQuery'. The 'maximum bytes per Read operation' quota (4096) has been exceeded while reading XML data. Long element start tags (consisting of the element name, attribute names and attribute values) may trigger this quota. This quota may be increased by changing the MaxBytesPerRead property on the XmlDictionaryReaderQuotas object used when creating the XML reader. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas
