SwarmAgent stopping with error

Hi,

I’m trying to build lighting for my project with 5249 unbuilt objects with “Preview” quality and lightmap res set to 4 on all foliage.

I’ve built lightning successfully many times in this project before, but when trying to now, I get the following in SwarmAgent:

[Interface:OpenChannel] Error: System.OverflowException: Array dimensions exceeded supported range.
at NSwarm.FSwarmInterface.OpenChannel(String ChannelName, EChannelFlags ChannelFlags)
07:13:31: [Job] Job has failed! Job executable didn’t exit cleanly. Exit code 2

My system:
i5-6600K @3.5GHz
32GB 2133MHz RAM
AMD Radeon R9 Fury

Up.
I have problem like that

Up. I have problem like that

Up again, I have the same exact problem on a 36 cores / 64GB machine in swarm with the same exact pc plus a few others. The project was building perfectly fine until it suddenly didn’t want to anymore.

Up. Exact problem, from some moment project suddenly refuse to build lighting with swarm.

Up, same problem

anyone have a fix for this?

Thank you for posting your question. From what I was able to find, the people who face this same issue typically attribute it to a high poly model or two in their levels.

Another resource for now is the documentation on Swarm itself.

I hope this information is useful to you.
