Hello melanie, I meet the same problem about request-id in log.
I think this bug is similar to cinder bug
https://bugs.launchpad.net/cinder/+bug/1743461 as Rikimaru Honjo says.
In his patch, eventlet.monkey_patch() must before import oslo_log (actually
before import oslo_context).
In nova, we do eventlet.monkey_patch() in nova/cmd/__init__.py but import
oslo_service in nova/__init__.py,
and in oslo_service will import oslo log.
In my environment, I delete the monkey_patch() in nova/cmd/__init__.py and put
it to nova/__init__.py before oslo_service.
In this way, the request-id (including the periodic task) will not be replaced
by other processes.
I think this maybe more suitable to close bug#1773102.
Tanks.

Bug description:
nova-compute imports oslo.context before calling monkey_patch():
(Pdb) bt
/usr/local/bin/nova-compute(6)<module>()
-> from nova.cmd.compute import main
/opt/stack/nova/nova/__init__.py(33)<module>()
-> import oslo_service # noqa
/usr/local/lib/python2.7/dist-packages/oslo_service/__init__.py(17)<module>()
-> from oslo_log import log as logging
/usr/local/lib/python2.7/dist-packages/oslo_log/log.py(48)<module>()
-> from oslo_log import formatters
/usr/local/lib/python2.7/dist-packages/oslo_log/formatters.py(28)<module>()
-> from oslo_context import context as context_utils
> /usr/local/lib/python2.7/dist-packages/oslo_context/context.py(40)<module>()
-> _request_store = threading.local()
which makes the global thread-local variable (_request_store) not
green. So instead of having request context per green thread, we have
one context for all green threads which is overwritten every time a
new context is created.
This is regression from this patch:
https://review.openstack.org/#/c/434327/
which imports oslo.service before eventlet
