Short description of error
Blender crashes regularly with Segmentation fault: 11" while rendering an animation

Exact steps for others to reproduce the error
This is not a neatly defined crash. While rendering a 2100-frame animation, Blender crashes regularly. With the release build, this seems to be every 100 to 200 frames or so. With a local compiled 2.81 version, the crash is more often, sometimes after 10 frames.

The .blend file is on a local SSD, the output (frame per image) is written to an SMB share on a NAS.

If needed, I can provide the .blend file.

Update: storing output in a local directory does not change the crash behavior.

I'm replicate this issue since I have the same hardware. Do you use EEVEE or Cycles? Will this happen if you render 250 frames of the default scene?

I am using Cycles.

I tried your suggestion with 2.80 RC2 build, the 2.80 official build and a local compiled 2.81.

Rendering a 500-frame animation of the default scene did not reproduce the crash.

A partial test with Eevee (approx 300 frames) also did not reproduce the crash.

Can you share something minimal that reproduces the crash?

I will try that as soon as I can and update here after 'elimination'.

It seems to have been a corruption in the .blend file.

I appended the components into an empty file and now Blender (2.81, local build) properly renders all 3000 frames in one go.

Can you please close the task?
