what change do you see as problematic?
i know it's typical for us to run with multi-gigabyte processes. so
assuming that the op has got a couple of gigs of memory and there is
no dastardly swap configured, it would be either
(a) something in the sources kernel has introduced a panic
(b) or something in go is tickling an existing panic.
but the changes i see all look to be corner cases, or startup
code which would fail on boot. i'm missing what change could
have introduced this.
i'd guess an old bug.
