May be the same root cause as #56793 (attn @golang/ppc64).

This could be related to the gcimporter changes in https://go.dev/cl/445455 (CC @matloob)

I suspect these failures around 9-10 Nov can be ignored. I was attempting to reproduce a gdb test timeout failure in a separate container which seems to have caused some spurious OOM kills on the P8/ppc64le VM.

Oops, wrong issue. 😅

I think the recent failure on the power10 builders is the OOM/container related memory leak. I'll reboot both once the current jobs finish.

The recent failures should be a new issue. Added a date restriction (#57632).
