Vram not releasing when rendering with slaves. Tweet

[JPhi]

Hi,

I am rendering the same scene with 3 stations and 1080 ti.

One is rendering alone.
The second renders as master and the third one is slave of the master.

When the scene is loaded in GPU and rendering begins, there is still some amount of free vram.
For the fisrt workstation (the one without slave), everything seems to be fine.
But for the two others, free vram slowly decrease as some new images are rendered. Then, when there is not enough vram, render longs for ours an never complete. No crash, but I have to quit lightwave, reload the scene again, and render agin to free vram.
The last line of the log before I stop rendering is :
>>> Draw preview image finished. Releaseing mutex
And nothing else.
And the slave daemon says it has not enough vram to load some image (I don't know how to crete a log from a slave daemon, so I had to close it and can't give the log).

I tried swapping workstation (the one running fine alone became master and an one other one slave) and the same things appears. So it does not seem to be related with workstation, but with master and slave relationship (or maybe this less intensive when no slave is used and I can render the scene before there is not enough vram).

Thanx for responding.

Hi,

forgot to say I use octane 3.06.4.

Thanx.

Thanks, I'll try to reproduce this problem here. it is weird because in the log memory reports I can't see the problem. Perhaps there is a memory leak in the render slaves.

In your log the memory related information about the last frame is <> Mem Used/Free/Total: 8725 / 1475 / 12288 ... enough to render the scene without problems, and seems stable among the latest frames. But this is the memory available in the local GPUs, not in the network rendering nodes.

Thanks,
