This floods syslog and everything else until the port issue is solved.
There are two problems, I think. One the log itself will flood and cause issues. That can be solved with a patch like follows (which I'll formalize and send upstream): diff --git a/vswitchd/bridge.c b/vswitchd/bridge.c index 2976771ae..0eebea144 100644 --- a/vswitchd/bridge.c +++ b/vswitchd/bridge.c @@ -1810,8 +1810,10 @@ iface_do_create(const struct bridge *br, *ofp_portp = iface_pick_ofport(iface_cfg); error = ofproto_port_add(br->ofproto, netdev, ofp_portp); if (error) { - VLOG_WARN_BUF(errp, "could not add network device %s to ofproto (%s)", - iface_cfg->name, ovs_strerror(error)); + static struct vlog_rate_limit rl = VLOG_RATE_LIMIT_INIT(1, 5); + if (!VLOG_DROP_WARN(rl)) + VLOG_WARN_BUF(errp, "could not add network device %s to ofproto (%s)", + iface_cfg->name, ovs_strerror(error)); goto error; } The second is that for "Address family not supported by protocol" we shouldn't ever retry the port (it will never be supported). That will take more thought, though.
At least, the rate limit log is posted upstream. https://mail.openvswitch.org/pipermail/ovs-dev/2019-September/362657.html
https://mail.openvswitch.org/pipermail/ovs-dev/2019-September/362924.html This patch was accepted. Let's see if it clears up the utilization problems.
