It can be ruled out that it is a memory problem, because I used "memtester" to test all night, and the results showed that the memory is OK.

Hey @ChaiWenyu1983! What kind of hardware specs do you have? (CPU, GPU & RAM). And also how did you build Lotus:

'+16-bit-insts' is not a recognized feature for this target (ignoring feature)
'+add-no-carry-insts' is not a recognized feature for this target (ignoring feature)

These logs make me suspect that you might not have built Lotus properly for your hardware maybe.

And also, what is the full lotus version - lotus -v?

Hey man,   lotus -v:lotus version 1.15.2+mainnet+git.518dc962e

What about this @ChaiWenyu1983? I suspect that it might be a build issue, so building from source again might fix it. Follow this: https://lotus.filecoin.io/storage-providers/operate/upgrades/#upgrade-in-place

Okay, I would consider changing the GPU if you want to do C2 jobs on the GPU, as the Commit 2 job needs more then 10GiB VRAM, so it will definitely fall back to use the CPU for the C2 job as is now.

So a couple more questions, and some things I would like you to do to troubleshoot more:

Questions:

• Is the specs for the C2-worker only? Or is this machine running everything (lotus, lotus-miner, workers, etc?)
• Are you using CUDA or OpenCL?
• What env-variables have you set?

Recommended things:

• Build from source: https://lotus.filecoin.io/storage-providers/operate/upgrades/#upgrade-in-place
• Change GPU to a GPU with higher VRAM (and not a LHR-card) if you want to do C2-jobs on them.

Also, I´m moving this issue to a discussion, as that is a better suited place for this kind of debugging.
