We are having a issue where users in our ECC6.0, HR ECC 6 and ECC 5 systems are having their connections dropped.
The errors from sm21 are as below:
09:49:00 DP Q0 4 Connection to user 4760 (NA001YO ), terminal 84 (NA001YO-DBY7) lost
09:49:00 DP Q0 4 Connection to user 5743 (JA001ON ), terminal 155 (JA001ON-STM2) lost
09:49:00 DP Q0 4 Connection to user 4807 (PA004PO ), terminal 94 (ER006CU-CLW1) lost
09:49:00 DP Q0 4 Connection to user 5665 (CH028LA ), terminal 145 (CDCWKS5-IND3) lost
09:49:00 DP Q0 4 Connection to user 4444 (WI005NE ), terminal 188 (WI005NE-DBY1) lost
Strange thing is at same time stamp, users are disconnected from many SAP servers.
1. Network is not intermittent or transient.
a. Not all users are affected on a server just some and they are from various sites around a fairly large region.
b. They can immediately reconnect without issue.
2. Firewalls do not show dropped connections.
3. Patches for the OS were put in place AFTER the issue started.
The systems are running on Windows Server 2008.
The event logs for the servers show the same information as SM21.
Client event logs Windows XP show no errors
The issue does not occur at any specific time, they do not happen to users at a specific location. Not all users on a particular application server are affected only some of them.
I have experienced the disconnection personally but, I cannot replicate the problem.

Hello Manish,
Do you get a SAPGUI popup when the disconnection occurs?
If yes,
Not SAPGUI but network.
If no,
SAPGUI issue.

Hi Manish
Is this any idle timeout setting has been define in the SAP system? and also kindly check the SAP Note 21971 - Connection between SAP GUI and application server terminated
and also you check the is this any issue in the network by using the NIPING program for reference SAP Note 500235 - Network Diagnosis with NIPING
Thanks

Hi,
The disconnect that is happening is not due to idle timeout, this is randomly happening for users and it even happens when users are actively working in SAP.
We have already tried NIPING, that too was disconnected. We had already involved cisco vendor and they have checked each and every network device and didnt find any issues.
