You just saved me so much time. Still having this issue in 20.5, and changing maximum threads to '1' has fixed my constant crashing. Thank you!

I'm glad to hear that! I just came back to also mention that Intel's 13th and 14th generation CPUs have problems as the recommended voltage is too high causing instability. They blame the motherboard manufacturers, you can read up on it by googling it. I've come across a lot of people who are not aware of this. I use "Intel Extreme Tuning Utility" to lower the "Performance Core Ratio" and that makes CPU intensive software more stable. That's probably why setting the maximum threads to 1 helps (unless you have an AMD processor and then it's on SideFX's side).

Also, are you using an intel CPU, like i9-12900kf and up? There are issues with those CPUs. For some rare applications, you have to disable 1-2 threads (Intel Extreme Tuning Utility is a good tool for this). I suspect that this is why it worked for me to change the maximum threads. Maybe if you're building a computer, go with an AMD CPU. They have a larger cache which helps too but I'm not an expert when it comes to CPUs.

I realize this is old but in case someone is searching for this problem, I was able to solve mine by setting "maximum threads" to 1. No change in rendering time since I'm using XPU. Very odd but at least I can render my sequences without it stopping every few frames with that error code. Hope it helps someone.

Note: This was an issue in 19.5 and 20. I didn't test if this "fix" worked in 19.5.
