Hi,

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:

  BB_NUMBER_THREADS="1"
  SSTATE_MIRRORS = "file://.*
http://sstate.yoctoproject.org/dev/PATH;downloadfilename=PATH
<http://sstate.yoctoproject.org/dev/PATH;downloadfilename=PATH>"
  BB_HASHSERVE_UPSTREAM = "typhoon.yocto.io:8687
<http://typhoon.yocto.io:8687>"

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.

Cheers,

Richard
