Other Errors

The following errors occur only rarely:

The SAProuter receives incorrect data. This can happen if the route is too short or if the system overlooks the fact that the connection is to a SAProuter rather than a backend connection.
The SAProuter receives the route information too late (TCP/IP connection setup was successful).
The SAProuter is the client and it receives an incorrect response from the server.
The SAProuter is the server and it receives the data from the client too early.
SNC not active for a forwards connection
SNC not active for a backwards connection

Incorrect data sent to the SAProuter

The log file contains the following entries:

Thu Jun 14 09:55:36 2007 CONNECT FROM C10/- host 10.66.66.90/34506 (host1.company.corp)

Thu Jun 14 09:55:36 2007 INVAL DATA C10/- route expected

Thu Jun 14 09:55:36 2007 DISCONNECT C10/- host 10.66.66.90/34506 (host1.company.corp)

The client issues the error message below:

          
*********************************************************************** * LOCATION SAProuter 39.1 (SP3) on 'host1' * ERROR internal error * * TIME Thu Jun 14 09:55:36 2007 * RELEASE 710 * COMPONENT NI (network interface) * VERSION 39 * RC -93 * MODULE nirout.cpp * LINE 2664 * DETAIL NiRClientHandle: route expected * COUNTER 4 ***********************************************************************

Explanation:

The client program sends incorrect data to the SAProuter. This is usually the case if the client assumes that it is already communicating with the target system but the connection was actually established to an SAProuter that has to wait for a route first.

Solution approach:

Check the parameters for the connection setup on the client.

Route sent too late

The log file contains the following entries:

Thu Jun 14 12:27:27 2007 CONNECT FROM C11/- host 10.66.66.90/35087 (host1.company.corp)

Thu Jun 14 12:27:32 2007 CONNECT ERR C11/- no route received within 5s

Thu Jun 14 12:27:32 2007 DISCONNECT C11/- host 10.66.66.90/35087 (host1.company.corp)

The client issues the error message below:

          
*********************************************************************** * LOCATION SAProuter 39.1 (SP3) on 'host1' * ERROR connection timed out * * TIME Thu Jun 14 12:27:32 2007 * RELEASE 710 * COMPONENT NI (network interface) * VERSION 39 * RC -5 * MODULE nirout.cpp * LINE 6519 * DETAIL RTPENDLIST::timeoutPend: no route received within 5s * (CONNECTED) * COUNTER 5 ***********************************************************************

Explanation/solution:

The connection setup (connect) was successful but the client sends the route to the SAProuter too late, or the client assumes that it is already connected to the server and is waiting for data, or the timeout -W is exceeded.

This error can occur if the client does not send the route quickly enough after the TCP/IP connect to the SAProuter. This might be caused by the client hanging temporarily.

Incorrect response from the server

The log file contains the following entries:

Thu Jun 14 13:59:43 2007 CONNECT FROM C9/- host 10.66.66.90/46915 (host1.company.corp)

Thu Jun 14 13:59:43 2007 CONNECT TO S9/17 host 10.66.66.91/3253 (host2)

Thu Jun 14 13:59:43 2007 CONNECT ERR S9/17 invalid data form server during route completion

Thu Jun 14 13:59:43 2007 DISCONNECT S9/17 host 10.66.66.91/3253 (host2)

The client issues the error message below:

          
*********************************************************************** * LOCATION SAProuter 39.1 (SP3) on 'host1' * ERROR internal error * * TIME Thu Jun 14 13:59:43 2007 * RELEASE 710 * COMPONENT NI (network interface) * VERSION 39 * RC -93 * MODULE nirout.cpp * LINE 2694 * DETAIL NiRClientHandle: invalid data from server 'host2' during * route completion * COUNTER 3 ***********************************************************************

Explanation:

If a server-side program other than a SAProuter responds, or if the back end responds, the SAProuter cannot use t he response. It needs another SAProuter as the server.

Solution approach:

Check the parameters for the connection setup on the client.

Data received too early from the client

If the SAProuter, as the server, receives data from the client before the route is established, the following entries appear in the log file:

Thu Jun 14 14:15:00 2007 CONNECT FROM C10/- host 10.66.66.90/52640 (host1.company.corp)

Thu Jun 14 14:15:00 2007 CONNECT TO S10/18 host 10.66.66.91/3253 (host2)

Thu Jun 14 14:15:00 2007 CONNECT ERR C10/18 invalid data form client during route completion

Thu Jun 14 14:15:00 2007 DISCONNECT C10/18 host 10.66.66.90/52640 (host1.company.corp)

The client issues the error message below:

          
*********************************************************************** * LOCATION SAProuter 39.1 (SP3) on 'host1' * ERROR internal error * * TIME Thu Jun 14 14:15:00 2007 * RELEASE 710 * COMPONENT NI (network interface) * VERSION 39 * RC -93 * MODULE nirout.cpp * LINE 2688 * DETAIL NiRClientHandle: invalid data from client * 'host1.company.corp' during route completion * COUNTER 5 ***********************************************************************

Explanation:

The client program is behaving incorrectly.

Solution approach:

Check for a more recent version of the client program.

Data received too early from the server

The log file contains the following entries:

Thu Jun 14 13:59:43 2007 CONNECT FROM C9/- host 10.66.66.90/46915 (host1.company.corp)

Thu Jun 14 13:59:43 2007 CONNECT TO S9/17 host 10.66.66.91/3253 (host2)

Thu Jun 14 13:59:43 2007 CONNECT ERR S9/17 invalid data form server during route completion

Thu Jun 14 13:59:43 2007 DISCONNECT S9/17 host 10.66.66.91/3253 (host2)

The client issues the error message below:

          
*********************************************************************** * LOCATION SAProuter 39.1 (SP3) on 'host1' * ERROR internal error * * TIME Thu Jun 14 13:59:43 2007 * RELEASE 710 * COMPONENT NI (network interface) * VERSION 39 * RC -93 * MODULE nirout.cpp * LINE 2694 * DETAIL NiRClientHandle: invalid data from server 'host2' during * route completion * COUNTER 3 ***********************************************************************

Solution approach:

Check the version of the SAProuter on the server side and update the program if necessary.

SNC not active for a forwards connection

The log file contains the following entries:

Thu Jun 14 17:16:40 2007 CONNECT FROM C18/- host 10.66.66.90/30891 (host1.company.corp)
