It doesn't seem to happen very often and I guess autobuilder doesn't
include meta-python2 (which is currently the only reproducer in my list
of layers).

I've tried to reproduce it with just 3 layers included:
BBLAYERS = " \
  /OE/build/oe-core/meta-python2 \
  /OE/build/oe-core/meta-openembedded/meta-oe \
  /OE/build/oe-core/openembedded-core/meta \
"

and it happened on 3rd try (cache, tmpdir, sstate-cache were removed
only before 1st try)

adds an warning to the stuck build:

WARNING: Cooker received SIGTERM, shutting down...

killing the main process:
martin@jama:~$ kill 943698

terminates the stuck build, but all bitbake-server processes are left behind.

If I try to kill all remaining bitbake-server processes, then only one is left behind:

and then it dies as well after a while.

Here is bitbake-cookerdaemon.log, but doesn't look very interesting to me:

It was reproduced on builder with 64 cores.

After changing BB_NUMBER_PARSE_THREADS from default 64 to 10, I wasn't able to get bitbake stuck again (in the same setup after cleaning cache, tmpdir, sstate again) by calling "bitbake python-native" 20+ times.

But after changing BB_NUMBER_PARSE_THREADS to 100 I wasn't able to reproduce it again (so maybe 3rd try with the default value was just me being lucky to reproduce it).

Then I've tried to change it to 1000, just to see what happens and it got stuck (but probably from different reasons):

Summary: There were 2 ERROR messages shown, returning a non-zero exit code.
martin@jama:/OE/build/oe-core$ bitbake -k python-native
NOTE: Reconnecting to bitbake server...
NOTE: No reply from server in 30s
NOTE: Retrying server connection (#1)...

On this builder I was using:
BB_SERVER_TIMEOUT = "60"
but that doesn't seem to be required to reproduce as the other builds I've seen stuck on jenkins weren't setting BB_SERVER_TIMEOUT at all.

Let me know if there is something else I should try next time it gets stuck, but right now
I'm not able to reliably reproduce it again (even after switching back to default BB_NUMBER_PARSE_THREADS)
