This is an OOM or timeout on netbsd/arm.

There is some general flakiness on the two NetBSD/arm build machines. It appeared around the time I switched from gobuilder to LUCI, and also from NetBSD-9 to NetBSD-10. I am still working on getting to the bottom of this, sorry for the noise.

One of the symptoms I am seeing (unrelated?) is that the machine sometimes gets some processes stuck in the "tstile" state. This mostly happens with gopls tests. I suspect a kernel bug, but debugging is difficult because the issue is intermittent.

There is https://gnats.netbsd.org/58871 on the NetBSD side to track this.
