It’s hard to make a clear statement wether we are facing a problem in the Rock PI 4 ethernet or a unappropriated eth0 settings.
The facts are that I run a Java program which works as an interface between 2 devices. Both devices they send lots of small pictures (1024x368 BMP) back and force plus loads of tiny telnet commands.
I would say the the lan is quite busy with tiny images and telnet commands.
The problems we are facing is that the 2 devices hang due too lack of reply on the commands they send.
It is a guarantee that the app works well. We already run the same app in a regular laptop and there was no single hang since days of work, while when we run it in the rock pi, it hangs several times a day.
In some other forums, people mention that the memory buffer allocated for the eth0 is way to small.
Not sure if Im looking in the right direction or not, but using Debian, how should I adjust the memory buffer allocated to the eth0.
I’m using more than 200 Rock pi per year, so things are escalating.
Would like to hear a piece of advice.
