Comment 3 for bug 1701222

I took the v4.12 kernel and compiled the LIS daemons from those sources as well.

Reloading the Data Exchange service, KVP will fail with the below message. This is the same as initially reported, so nothing changed in the behavior.
Not sure on the regression part, only up to the point on differences between distributions.

KVP failure with v4.12 and
Jul 6 01:18:55 xenial KVP: read failed; error:9 Bad file descriptor
Jul 6 01:18:55 xenial systemd[1]: hv-kvp-daemon.service: Main process exited, code=exited, status=1/FAILURE
Jul 6 01:18:55 xenial systemd[1]: hv-kvp-daemon.service: Unit entered failed state.
Jul 6 01:18:55 xenial systemd[1]: hv-kvp-daemon.service: Failed with result 'exit-code'.

After this error when systemd tries to start KVP again, if I manually do #systemctl start hv-kvp-daemon.service then the daemon will start just fine.
