There are several customers of ours using SLES under database servers and for a few weeks their network connections have been crashing while server machines which SLES installed on in the same lan. Every customer has one server machine in their LAN. (Individual customers + individual LANs + individual internet routers etc.)
If server machine is not in the lan everything goes well but when we switch it to the network it causes a network overload and internet connection reduces by almost 99%.
Is there any action you would suggest us to perform in order to determine a proper solution for this problem.
