What does the log file say?
Hi Lee, tx replying. Attached is log file. I set it to output debug.log-win.txt
Also attached is the previous render log- a successful one.logsuccess-win.txt
On a mac it crashes at the same point, but says illegal memory something ( sorry not at that computer )
I have also tried optimising the file before rendering.
What is crashing? The render, or noice?
noice is a separate process that you run on the files that were rendered.
Or do you mean that the crash happens only when you enable Output Denoising AOVs?
Hi @Stephen Blair Noice - the seperate after you render is working. BUT I can t render a sequence to begin with - well more than a few frames. So its the initial MtoA render with the enabled denoise box ticked. Another odd thing is - the render viewport window that shows the progress of the render seems to show different AOV's - or at least some of them, in a cycle - render 1 is Beauty, Render 2 shows the Z Aov, Reneder 3 shows the Normal AOV , Render 4 shows Beauty, Render 5 shows Z Aov , and sometimes it shows the Variance AOV and so it goes ..... till it crashes 🙂
Normally - ie with no denoise output aov the render window just shows the beauty AOV.
Just found a mac log file
initializing 407 nodes ... 00:00:06 4229MB ERROR | signal caught: SIGABRT -- Abnormal process @Lee Griggs
if that helps.
Ok, so the crash has nothing to do with denoising.
The shifting AOVs is a known issue, but it doesn't cause a crash.
Impossible to tell why it crashes. Can you post a simplified scene that reproduces the crash?
Hi @Stephen Blair, link to file, and last 2 logs of test. The render sequence went for 45 min (the last log is crashed)

If Arnold / Autodesk etc has a file that they know doesnt crash I m happy to test that if someone can send.
Hi @Stephen Blair, I have tested another scene on a windows mechine and received a error initializing 196 nodes ... 00:00:10 4788MB ERROR | signal caught: error C0000005 -- access violation.. I searched this and see there are other posts with this error - although you have said its a vague error. they all seem to be unresolved.
Just checking for a response @Stephen Blair - is there actually an official support system?
Do you have Arnold subscription and support?
signal caught: error C0000005 -- access violation
Could be anything.
Try to isolate the problem. One approach is to enable all the Ignore options (Render Settings > Diagnostics). If you don't crash, then re-enable one by one until you do crash.
Another approach: start removing things from the scene until the crash stops. Then you have an idea of where the problem is.
Hi Ju Wo: I'm with the same problem here, and losing my mind to solve it. Did you find a solution for this? I don't find more information than your comments. Thank you!
