SwarmAgent stops working after photon caching

Hi, I’m using distributed rendering with swarm agent. My remote machine always stops after finishing photon caching and never works for the “Processing Mappings”.

18:53:26: Lightmass on PC-PC: 1:17 min total, 9.01 sec importing, 3.25 sec setup, 1:04 min photons, 2 ms processing, 0 ms extra exporting [0/38 mappings]. Threads: 87 ms total, 0 ms processing.

Any suggestions? Thank you!

Have you tried the steps from this answer?

Thank you .

I updated to 4.11.1 and part of the problem is solved. The remote agents can now work for the “mapping processing”. But they still stop before the entire baking is finished.

My experience from other distributed rendering solutions(e.g. Vray) is that all the render nodes should work together until the whole rendering job is done. But my swarm agents just stop working after a while and leave the rendering job to my local machine. The total rendering time is about 1600 seconds, the agents worked for only 200 seconds. There are enough space for cache. Is this normal for lightmass building?
