Client loses Connection occasionally with server

[cofelyhoogland]

Hi,
We have connected two clients to the WINCC-OA Scada server.

One client occasionally lost connection with the server .

This is the log of the server:

Would anyone happen to know what this warning message means and how it can be fixed or prevented?

In case of a connection loss you always have to look at the PVSS_II.log file for the server and the client.
"Connection reset by peer" simply means that the communication partner (peer) has closed the connection.
