Trying to figure out random crashing

Been working on a job the past few days and have been experiencing tons of random crashing that seems related to when certain things are clicked in the user interface.

Sometimes it's by closing a spline there will be an instant crash.

Or sometimes toggling the viewer Gain and Gamma

Things like that. though it's not all the time, and I haven't been able to isolate what is making it happen, but I thought I'd post a crash log in case anyone who knows more about this sees anything pop up. Would love to know at least WHY it's happening. All OpenCL is turned off in Preferences.

I notice you have SIP disabled on your iMac Pro...likely because you are using an Nvidia eGPU.
You are probably exceeding the stack space allocated by the OS. My guess is you need better 'hacked' GPU drivers.

The SMBios is an iMac Pro but this is actually a Hackintosh with internal 1080Ti's.

Don't know what SIP is but maybe I can enable it?

SIP = System Integrity Protection.
Enabling it will cause the OS to replace any tampered core files from an image the next time you boot. Since it's a hackintosh you probably don't want to do that.

Do some googling for: "segmentation fault 11" hackintosh nvidia

You may also want to decrease the RAM allocation in the memory section of Fusion's Global Preferences...see if that changes anything.

I've got 128GB of RAM and am nowhere near full with it so I don't think it's RAM thing?

Maybe. Maybe not. It could be GPU memory or something else entirely but it's impossible to tell without first narrowing down from the most obvious.

Gotcha.

Here's what it is now

Are the crashes happening all the time with any comp or just a specific comp?

All the time with any comp.

It's not that it happens every time. But basically, I know if it's been about 15-20 I'm about due for some random crash just by clicking something.

hmmm....could be a large number of things including other running apps. Are you running any OS plugins that use code injection (such as SIMBL plugins)?

I don't believe so. Is there any way to check?

You would know if you were...unless of course perhaps it's an app related to your hackintosh configuration or something.
I'm on a genuine iMac Pro so can't help in that department if that's the case.

The next thing to try is this:
Create a new user profile in system preferences.
Make sure your project files if on the same system are available to the new user by sharing or changing the permissions.
Log out of your current profile completely and then log into the new profile.
Go through the setup as usual.
Then open Fusion and work for a while and see how it goes.
If all is well then you may have some corrupt files in your user library somewhere.

The next step will be to try and reproduce with a fresh OS install with just fusion added (can be on a separate disk).
If it still continues to crash then you've got a hardware problem or it's something related to the hackintosh setup (drivers or otherwise)

Hi there,

I have a macPro ashcan, 8 core Xeon E5 32 GB ram and I have been experiencing random crashes too. Sometimes it hapens when opeing a comp, or when selecting a node to view or when starting a render. Changing parameters on a node can also cause a random crash. I'm on Mojave and I think it might be to do with that. I have had to turn off openCL which reduced the incidence of crashing. BTW SIP is enabled on my system.

Cheers
Ziggx

Here's another crash log from a crash that just occurred right now by closing a spline. Something that's been happening often on this current cleanup project.

It's a memory allocation error. A pointer to a block of freed memory doesn't actually point to free memory causing data corruption. This could be caused by Fusion but could just as easily be caused by some other app/library.

Added in 6 minutes 36 seconds:
@ziggx random and infrequent crashes are somewhat normal but harder to troubleshoot. Frequent and consistent crashes like @bowserlm is experiencing are not and I suspect in this case that it is somehow related to the hacked OS...can't really be of much more help here, sorry.
