Hi,
I have the same ram issue as OP.
This happens every time when team rendering. The ram usage creeps up over time until it reaches, in this case 149GB!!, and C4D becomes unresponsive. (See screenshots)
I have about 650GB available space on my boot drive, but the swap file size must have a “hard” limit.
Not sure what role Apple’s mysterious “kernel_task” plays in all this.
No multi-passes used (I always render multi-passes separately)
Just 1 render client used, on 1 Gb LAN
2 identical machines with 64GB ram
No other major process running.
Around the same time the “low mem” warning pops up, the client always disconnects “greenlights” in machine list. Uncheck/check brings the client back online and renders for a bit, till it disconnects again…
Could this be some kind of memory leak in Team Render? I was able to save a CXR before C4D crashed, rebooted, “Resume from file” and continued rendering the image.
The render finished at the set 3% noise level while only using around 27GB of ram the whole time.
“Resume from file” renders only on the main machine, a “Team Render from file” option would be great, once Team Render becomes really “useable”.
For me, the growing ram issue happens with every scene I teamrender, but depending on image size the render might just finish before c4d crashes. 3000x2000 is on the safe side, but 4500x3000 is pushing it.
I’m currently in a bit of a deadline crunch, but I can prepare a scene w/ assets once I have some time, if that helps. I assume I need to strip out all plugins like Laubwerk etc before sending.
Maybe, if the C-Team creates a sticky post with a sample scene that users can download to test TR, with instructions of what you need to see, might even give you a better insight into what’s happening.
Nevertheless, it’s time to say Thank You! for all the wonderful work you guys did so far with corona.
Hope that these team render issues can be ironed out before final release.
All my best.
Frank
