I've seen the same for some time now when building core-image-minimal
with yocto state mirror and hashequiv servers.

After some investigation I think the root cause is some
bandwidth/connection limitation on the http yocto mirror.

Reducing the BB_NUMBER_THREADS="1" to a single core solves many of the
fetch issues for me,
my config is the default one with:

  SSTATE_MIRRORS = "file://.*;downloadfilename=PATH
Oops, it seems you're right. I have the same SSTATE_MIRRORS and
BB_HASHSERVE_UPSTREAM settings as you do, and adding
BB_NUMBER_THREADS="1" makes the errors disappear.

It seems I should file a bug about that. The error messages just mention
local paths, not remote ones, so it sounds like a local issue while it's
apparently not.
That is useful to debug it but suggests there is an issue with concurrent
connections to the YP server.

I think we should have an open bug and get Michael Halstead's input on this.

Thanks for your advice.
