Strange Gateway Error with one APP Server (WSAETIMEDOUT)

Hello Everyone,

We are experiencing a strange gateway timeout issue on one application server in our SAP environment. This started happening after we applied a series of Microsoft patches and updated the SAP kernals from 179 (DB 172) to 185 (DB 182).

From this App server we are seeing all kinds of gateway errors, the following is a sample from the dev_rd file from the server in question:

LOCATION SAP-Gateway on host sappe1exp5 / sapgw00

ERROR partner 'sappe1exp4:sapgw00' not reached

TIME Sat May 30 23:40:54 2009

RELEASE 700

COMPONENT NI (network interface)

VERSION 38

RC -10

MODULE nixxi.cpp

LINE 2823

DETAIL NiPConnect2

***LOG Q0I=> NiPConnect2: connect (10060: WSAETIMEDOUT: Connection timed out) [nixxi.cpp 2823]

      • ERROR => NiPConnect2: SiPeekPendConn failed for hdl 6 / sock 428

(SI_ECONN_REFUSE/10060; I4; ST; 10.10.0.21:3300) [nixxi.cpp 2823]

I have done alot of searching and I have tried the following things:

1) Checked the services file of this machine, they line up with all other systems

2) Attempted to telnet to other App servers on 3200, 3300, 3600 with no success

3) tried to connect via SM59 to another App server with no success

4) Attempted to do all of these things in reverse from the another app server with the same results.

This is only happening with one app server in our landscape and this app server has no issues connecting to the CI.

Any ideas on where I can look further?

Hi,

on sappe1exp5 try the following command in a dos prompt:


telnet sappe1exp4 sapgw00

this should also time out i.e. hang for a certain amount of time (~50 seconds) and then terminate with error.

It simply means that the IP address 10.10.0.21 is not reachable from your client PC.

Maybe you changed some IP addresses during patches. Usually there is an RFC destination that is not functioning properly.

Hi James,

You have updated microsoft patches so please check below link , it maybe your problem

Also check

1. Increase the trace level of the gateway log from TCODE SMGW

2. Check with Network team if everything is OK with App server in issue, looks like a DNS or proxy network issue.Make usre DNS name is getting resolved properly.

Thank You,
