In weblogic logs we see below errors many times while accessing application
input/output error: java.net.SocketException: Connection reset
Could not deserialize session data
These are some of the most common causes of the “connection reset” error:
The client browser was refreshed or closed. If the error message is reported because of this condition, it is often because there may be performance issues in the system. To solve the problem, find the bottleneck of the poor performance and eliminate it.
There’s a firewall between the client and WebLogic server, and the connection was dropped by the firewall. For this scenario, please set up the firewall properly. Network congestion makes the operation timeout. Relieve the network congestion and the problem should resolve.
