[Kirill Zaitsev]

We're using kuryr-kubernetes and os-vif. Here's the complete error log

further investigation showed, that msg's value during out_of_band is `(6, 20, u'privsep daemon starting')`

[Kirill Zaitsev (kzaitsev)]

Simply removing 'LOG.info('privsep daemon starting')' fixes the issue for me

[Kirill Zaitsev (kzaitsev)]

Seems that the bug is not present in the latest versions of the libraries

[Kirill Zaitsev (kzaitsev)]

Actually I'm still getting it on the freash install with oslo.privsep==0.22
