Bug Description
After updating Neutron from Queens to Ussuri we started getting the errors "OSError: Premature eof waiting for privileged process" for all of neutron agents and for different operations (create network, enable/disable dhcp etc.). All errors raises inside librari oslo.privsep which was updated from version 1.27.0 to 2.1.2 [1]. This problem is floating and very difficult to debug, it is impossible to understand what exactly is happening. The problem is consistently reproduced by tempest tests in our infrastructure.
Environment:
Neutron Ussuri, ML2 plugin + linux-bridge + custom agent HPB.
The examples of tracebacks: http://
(amotoki - paste.openstack.org is easier to read compared to launchpad description, so I moved the example traceback to paste.openstack

Hello
Just by curiosity which version of python are you using?
Ussuri support 2 versions for oslo.privsep which depends-on the python version used.
