Network connection to SAP system broken

[Former Member]

Hi!

I have the problem that all the connections with SAP systems after ca. 5-10 minutes will be automatically disconnected.

I connect from Windows XP SP2 with SAP GUI 7.10 (Patch 14 ).

The error I get:

SAP GUI 7.10

Connection to partner 'IP-adreess: 3299' broken

WSAECONNRESET: Connection reset by peer

Can some one help me to solve this problem?

Thank you!

This is not a SAP problem but a fundamental network problem.

Check your network connections, switches and network cards.

Hi!

Do some sap notes exist for this problem?

Thank you!

Holger,

read my answer again. You have a network problem.

SAP is an application running on your operating system and relies on a network connection. If that connection breaks then the SAP system or the GUI can't do anything about it. What you see is the reaction of the GUI telling you, that the connection to the server broke. The OS couldn't send network packets to the server because it was no more reachable.

So you have to fix your network. You can e. g. run a

ping - t <server-IP>

on your local desktop and see if the connection is still there when this error occurs. Check the server event log, check your switches/hubs and whatever network infrastructure you have. You can run a network monitor (e. g. wireshark) to see if you e. g. see any double IP addresses.

Again, this is not a SAP problem.

Hi Holger,

Please provide the result of ping to SAP server.

Is the SAP installed on a remote system?. Do you have access to that system?

Please reply to this.. It wil be helpful to understand ur problem better.

Hi!

The commando ping -t <server> looks fine:

answer of <server>: Bytes=32 Zeit=3ms TTL=62

Unfortunately the SAP GUI 710 error exist:

<SID>: connection to partner 'IP:sapdp01' broken

Module: nixxi.cpp

Method: NIRead: P=IP:3201; L=0.0.0.0:1:1358

Return Code: -6

System Call recv

Error No: 10054

Error Text: WSAECONNECT: Connection reset by peer

Still a network issue. Something is tearing down the connection and the SAPGUI is reacting on this.

Try using NIPING to diagnose your network issues. Judging by the disconnection of your clients my guess is it could be your firewall causing the problem.

Check [Note 500235 - Network Diagnosis with NIPING|https://service.sap.com/sap/support/notes/500235] for further information.
