Looks like this is happening somewhat frequently over the last two weeks, happening in 4.3, 4.4, and upgrade from 4.2

host-local is coredumping

Also something from openshift-sdn

Comment 3 Casey Callendrello 2019-12-10 14:38:58 UTC
The problem is that openshift-sdn is executing the host-local plugin installed on the *host* by multus.

We should stop doing that. We need to package our own host-local and stop using the bind-mounted one.

Phil, can you get to this today?
