Network freezes now and then

nothing really related to the software. I´m using a quite complex artnet network but during programming and playback the network freezes sometimes which can´t happen on showtime this weekend.

I have a ma3 onpc system with a qlab connected to the eachother via OSC in a network switch at foh. Then from the switch i needed to run the artnet via 100m utp to the node on stage which then divides in another switch to the resolume video server and 4 epix drives to run 64 strips.

If i broadcast then the epix flickers but the lights run smooth. If i unicast to the node and make a second line to unicast the video server then the flickering stops but then the network freezes and drops sometimes.

Any pointers where to look maybe? I guess the lenght? In total i have 71 universes so artnet should be able to run all that stuff normaly. Thx!

Is the cable actually 100 Meters, though that is technically valid it's almost like driving on the autobahn without a seatbelt, it might be fine, until it's not.

I'd try adding another switch (provided you have less then 7)1/2 way if you can or somehow reducing that length.

I've also had luck in a pinch on long cables configuring the switch to 100mbps links provided you don't have anything that requires 1gbps

Yeah it was a rol of 100m in 1 piece that goes from foh switch to backstage switch. Going to try to reduce the lenght somehow. I need fiber but the rental company doesn´t have it but are going to invest in it now

And the 2nd line is connected to the same switches? A big NoNo - you are creating a short circuit since the switches have to decide which line they will actually use.
2nd guess: 1Gb over Cat 5 at 100m is also asking for trouble. UTP vs FTP also makes a huge difference.

Edit: i see what you mean. But i don´t mean fysical lines. Just a second line on the MA artnet config tab.

Normaly you can unicast 2 devices on the same network, no?

fixed it with a seperated utp for the lights. So the artnet utp controles the resolume server en and epix strips and the new utp is sACN to the node for the lights.
