After Effects aerendercore randomly crashing

I'm using an applescript app that launches multiple .aep files to multiple outputs depending of each composition name attributes, sometimes I use this to launch multiple instances of aerendercore to render the same .aep:

The thing is that many times, I can't complete these task because the process aerendercore crashes at totally random.

The first on is quite common.

I'm lost here, is there any particular reason this is happening? These are my specs:

Im using After Effects version 15.0.1 (Build 73), my .aep projects are mostly vanilla except for some Animation Composer effects.

Hello,

Can you control the number of frame per core for rendering by your scripts? You try to change the number if you can.

Thats a interesting question, Im not sure if I can do that, I’m wondering now:

Can aerender control the number of frame per core for rendering?

Here are the scripts Im using, they may need to be changed in order to work in other computers, specifically the directory locations.

They work using ffmpeg and iTerm

https://www.dropbox.com/s/ar0kirsfhdsdpjp/For%20Adobe.zip?dl=1

The one called for-adobe.applescript is the one I use to start the whole rendering and encoding process

And the one called MultiCore.app is the one I use to initate multiple aerendercore instances.

for-adobe.applescript can be edited using OSX script editor

MultiCore.app can be edite using OSX automator

Hello,

I am not sure the specific cause. My guess is the overload or the memory overflow. After Effects might be confused to set the priority of the rendering. Does your After Effects become more stable when you decrease the number of the instance?

After doing some tests this week, I found that the crash only happens when using the Multi-Machine Settings (RS) and Multi-Machine Sequence (OM).

Rendering directly to .mov (ProRes LT) doesn't cause any crash

But I still need to render to PSD's, ironically, for error proof, since is easier to delete only the frames where I need to make changes, no need to render everything.

Also, invoking multiple instances of the same .aep as "Multi-Machine Sequence" gives me 3x to 5x more speed than sending a single aerendercore process to render a .mov.

Yet, even using 1 single aerendercore crash when using Multi-Machine Sequence.

Hello,

Have you already solved the issue?

No, the aerendercores still crashing randomly.

The Applescript I made allows me to revive the aerendercore process until all PSD’s are complete (by comparing the length of the audio and the length of the rendered video).

But still, the crashing still occurring.

Well, while someone in adobe figures out why this is happening, I had to add to my current applescript workflow, a function that detects if there are missing files and files that are 0 kb in size, and it will keep rendering until such files are gone (meaning all the PSD’s files exists in the folder).

If someone finds it helpful:

Here you can find the download link for the applescript: https://cl.ly/3y1L3Y1w3g23/download/CHECK%20IF%20MISSING%20FILE.scpt

Hello,

The warning happens in the folder called CACHES. Is it a real cache? How fast is your RAID volume? Do you render the sequential images or a single movie file like *.mov?

DG. David EscalanteAuthor

Kinda, all After Effects caches (Disk Cache and Conformed Media Cache) are stored into that drive which is a dual RAID 0, which is also where all the psd's multi-machine sequences are also stored.

I render using multi-machine settings (PSD's):

set P3renderPSD to (AErenderengine & " -project " & inputFilePath & " -comp " & AEPname & " -RStemplate 'Multi-Machine Settings' -OMtemplate 'Multi-Machine Sequence' -output " & RENDERfolder & "/" & AEPname & "/[#####].psd")

This is my RAID STORAGE drive speed:
