Comment 5 for bug 1827264

We catch this problem about a couple of times a week and have found a pretty non-trivial way to fix it quickly.

In crontab: watchdog_openvswitch.sh

#!/bin/bash

timeout 10 ovs-appctl version &>/dev/null

if [[ "$?" != "0" ]]; then
    echo "run strace for fix openvswitch"
    timeout 5 strace -f -p $(cat /var/run/openvswitch/ovs-vswitchd.pid) &>/dev/null
fi
