Thanks your advise ! But i Just checked the remaining disk space of the failed CI using df -h and found that 47GB of space was still available after the run. Additionally, I discovered that this issue is not limited to linux/x86, as this action also occurred in linux/arm64.

Maybe machine resource limit.

and i just test in my local docker container with ubuntu24/arm64, and i have remain 171G space, have the same error,so i think it's may not be resource limit.

reproduce

1. with the docker file https://github.com/luoliwoshang/DockerFiles/blob/v0.2.0/ubuntu/normal/Dockerfile
2. cd /root/llgo
3. count=1; while go test -count=1 ./...; do echo "=== Run #$((count++)) completed ==="; done
