Comment 11 for bug 1652934

Agreed with Oleg on this: the latest repro seems to be a different problem with OVS.

I took a look at the original diagnostic snapshot and looks like all the failures are consolidated on the node-3. It's not entirely clear to me what went wrong around 00:52:40 on December 28, but looks like after that nova-compute became buggy, e.g. the periodic tasks were not executed anymore. At the same time atop logs look fine, although there are some weird errors in syslog:

Waiting for another repro and a live environment.
