Short description of error
trying to bake high res mantaflow sims ( both fluids and gas/smoke ) crashes blender and prevents restarting of modular caches

18.blend

Exact steps for others to reproduce the error
load the attached blend file and bake sim.

from reading other similar bug reports I believe this may be related to AMD cpus ( i am on threadripper 2970WX with 64 GB RAM ) but cant know for sure.

I have not,
I only put him as assignee in hopes of getting some attention on this bug report as there has not been any since I posted it.

how many frames before crash happens ? 400 res is going to take a long time..
Also, try:

Rename C:\\Users\\((USER))\\AppData\\Roaming\\Blender Foundation\\Blender Blender folder to something like blender_backup.
Run blender_debug_log.cmd and get a crash
upload blender_debug_log.blender.crash.txt the path of which would be at the end of blender_debug_output.txt
rename the folder in step 1 to get back your settings.

I baked frame 1 to 8 on f7b22fc3d2 debug build and 1- 30 on 2.92 release and no crash so far.
macOS 10,14.6, intel i5, Intel hd 6000,

.. from reading other similar bug reports ..

Could you mention them ?

There's 2 other active reports for something similar: #86053 (from the comments, seems that not using blosc compression works around it) and #88120 which hasn't had user input in a while.

Sebbas made a change recently to at least workaround the blosc issue it looks like: 8dd43ac23e

Perhaps it's worthwhile for Ramon to try either Zip or None compression if he's the only one able to repro just to rule that in or out.

Can your file be simplified, so it takes less time to check? I gave up after 50 frames too. I can let it work at some point but to debug this it may be better to have as fast crashing case as possible.

Would like to gather info on whether this is resolved in 2.93? (because the suspicion is that 8dd43ac23e already fixed this.

Apologies for the lack of replies, Just tested the file and still crashing. It gets to about 70 frames before it just closes ( no screen freezing ) I have a suspicion that it is a scale issue as smaller sims even at these higher resolutions do seem to be more stable.

I can't reproduce after baking 75 frames.

I have looked at blender_debug_output.txt just now and noticed that there is frame change handler which may cause issues. Also bunch of other addons. I wouldn't expect scale to cause issues. High resolution seems more likely, but I would suspect some addon in this case.

@linxi Can you click on File > Defaults > Load Factory Settings and re-check if the crash happens?
