I think that is an OOM on our builders with newer kernels. The linux ppc64/p9,ppc64/p10,ppc64le/p10 VMs running a newer kernel are slowly leaking memory each time a container starts and stops.

I've poked at it a few times, but haven't been able to figure what is leaking. Something is holding onto percpu memory in the kernel, but not on every container cycling.

I've rebooted the ppc64/p10 VM.

From the last message, it seems like this might be builder-related? Tentatively dropping this from the compiler/runtime queue.

@mknyszek mknyszek added Builders x/build issues (builders, bots, dashboards) and removed compiler/runtime Issues related to the Go compiler and/or runtime. labels May 17, 2023
