OctaneServer Prime Crashing Randomly

[DarkCat736]

Hello!
I am using Octane Render Prime with Blender and I created a scene and then tried to render it, however after rendering a random amount of frames (usually 2-10) the render view has an error message reading "Error in render server" and the OctaneServer crashes. If I restart the server and have the render pick up from where it left off, it will continue rendering for a couple frames before crashing again. The system resources don't go above 50% and I couldn't find any logs so I'm not sure what is wrong. Does anybody know what might be happening? Thank you!

Have the same issue. Rendered one whole 250 frame animation today. After trying to render another one, the server keeps crashing after 4-16 frames. Restarting neither the server nor pc solves the issue. Didn't do anything specific to the file between rendering the animations. Definitely seems like a bug

Hi Kiran, you’re not alone — this looks like a known instability with Octane Render Prime in Blender. Many users report random server crashes between frames, likely a Prime or driver-related bug rather than a scene or hardware issue. Restarting usually doesn’t fix it, so updating Octane, GPU drivers, or switching render modes may help.

Having same issue, random server crashing when screen goes to sleep. Latest driver 595.79 & blender 5.0.1

Try updating your GPU drivers and Octane to the latest versions. Also, check if switching render modes or disabling sleep mode on your system helps stabilize the server.

Looks like it might be GPU/VRAM related. Try updating drivers, reducing scene complexity, or enabling out-of-core memory in Octane—those usually help with random crashes.

It seems that you have a classic instability of the Blender + OctaneServer connection, and according to the description it is more like not an overload of resources, but a failure of the render server or driver layer. Also an important point: if this is the Prime version, it sometimes has tighter stability limits compared to Studio/Enterprise. This is almost certainly either a memory leak or a GPU driver conflict, and not a normal scene error.

By the way, in such GPU rendering systems an analogy is often drawn with risky computational tasks: as in online gaming systems or casino services with bets, there is also a moment of instability and unpredictable results with a large number of repetitions - the system may crash not from the load, but from accumulated small errors in the process.
