Other Error Codes


10001 - Server Response Missing Status

  • The response received does not match the HTTP standard. All HTTP responses are expected to have a line in the header or body, in the following format: HTTP/(version return code) This will happen randomly on an object. Confirmation that the object downloaded in the browser is received if the number of bytes downloaded is greater than 0.
  • Sample status lines:
    • HTTP/1.1 200
    • HTTP/1.0 302
    • HTTP/1.1 404
  • If this status line is missing from the HTTP response, it will be reported in Gomez Networks as: 10001 - Server Response Missing Status Line.


10052 - Network Reset

  • The TCP connection was reset as the network connection was lost by the Agent.


10053 - Socket Connection Aborted

  • The Agent connection to the Web server was reset by the local system. This usually occurs when the Agent does not receive an appropriate response to an attempt to close an open TCP connection.


10054 - Socket Connection Reset

  • A TCP connection that was successfully opened has been reset by the remote end. This error may be caused by a server reboot or by a server process being restarted.


10060 - Socket Connection Timeout

  • The Agents attempt to open a new TCP connection to the remote server timed out. The timeout value is set by the Agents operating system, and occurs 21 seconds after the attempt to open the connection began. This can occur due to high levels of packet loss on the network path between the Agent and the remote server or because the number of incoming connection requests exceeds the servers current capacity.


* 10061 - Connection Refused

  • The remote server has refused the attempt by the Agent to open a TCP connection.


11005 - Connection Time Out

  • The Agents attempted to open a new connection and an ICMP message was returned from some point on the network path indicating that the port being connected to was unavailable through the known network path.


12000 - Socket Receive Timeout

  • The connection has been dropped by the Agent as no response has been received from the remote server on a TCP connection that is already established. By default, this timeout occurs at 60 seconds.


12004 - Invalid URL

  • The URL that is about to be requested is not constructed in a valid format. Examples of this include: URLs containing spaces or other illegal characters.


12013 - DNS Lookup Failure

  • The attempt to resolve the host name into an IP address failed.


14001 - Byte Limit Exceeded
