Using MQX 4.0.2, have an issue that after about a day or sometimes longer the ethernet port gets blocked. We use the ethernet port to connect to the application and the application using a ECB port to send and receive messages.
We use a python script to connect to our application, based on MQX, using a socket connection and when it has been running for some time it is not longer possible to connect. It is possible to ping the application and after the ping it is possible to connect for about a minute and then it gets blocked again. The application itself is running and is sending and receving messages but it is not possible to connect to it.
