Google found this old thread...

A co-worker is encountering this problem now as well on oe-core-2.4.


Srikanth,

Did you ever manage to identify the cause or a work-around?

Of course if you ssh to localhost and then do the build
that will work-around the issue.

More when we've had a chance to narrow down
the issue now that we have a system where we are
able to reproduce the problem.
