Swarm nodes keep restarting with a complex scene

I have a fairly large scene for which I am trying to build the lightmass. When rendering on production, my swarm nodes seem to get into a cycle of restarting, and they never actually help with the build. I attached an image…at any point before they can reach the ‘processing mappings’ phase, they will start over with the ‘lightmass starting’ phase. They do work when I change the lighting quality to preview, but they continuously fail and restart on production. I’m also including a snippet from the log at the bottom of this post from one of the nodes. It seems like the connection just dropped without reason and it just gave up.

These are purpose-built render nodes. They have 64gb of ram and they don’t even come close to reaching that limit. I’m wondering if anyone else has had similar problems and if there is something I’m missing or a setting I can tweak to prevent this from happening.

Thanks in advance,
-Ben
