Hello Richard,
I was under impression that installing Ubuntu-14.04.4 (+lastest
updates) would give me stable build environment, unfortunately that
is not the case ! I could see the logout issue on this installation
too. So I believe that issue should be reproducible on any 14.04.x
installation including 16.04.x with all latest updates installed. The
second attempt of build on "Ubuntu-14.04.4" shows the status of
bitbake as halted at libvorbis when logout happened:

None of these look particularly suspicios for causing your X session to
die.
Some further questions:
a) Is anything showing in the dmesg logs? Is the OOM killer the thing
which is killing processes?
b) How are you measuring free memory? You mentioned it was low, it
would depend on the disk cache size and swap status too.
c) Have you tried a lower BB_NUMBER_THREADS and lower PARALLEL_MAKE
values to rule out resource problems and perhaps identify more
specifically which task is causing your problem?
As I mentioned previously, this problem should reduce to a specific
recipe+task causing the problem, unless its a general resource issue in
which case the threads/parallel make will stop the problem occurring.
We have autobuilders running various versions of Ubuntu and we don't
notice problems with processes dying, admittedly we don't run X
desktops on them in general though.
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.

Cheers,
Richard
