unreacheable over ethernet after some time

[tommichiels]

Hi,

 

I have a stack of two master bricks and a POE brick.    I configured the ethernet with a static address.    After a few minutes the brick becomes unreacheable over ethernet.    According to my switch, the port is still on.  I can only bring it back to life by unplugging/replugging the POE cable so the brick reboots.

 

How can I debug/resolve this?

 

Thanks,

 

Tom

The first idea that comes to mind: The Ethernet Extension only supports a limited number of concurrently open sockets.

 

Do you open several sockets at the same time? Or maybe, do you not close a socket and instead of reusing it open a new one?

 

This can happen if you create new IPConnections instead of reusing/closing it.
