Estoy sufriendo desconexiones aleatorias con OpenVPN. No sé mucho sobre el tema, ¿tal vez puedas orientarme en la dirección correcta? Aquí está la cola de /var/log/messages, contiene una <warn>y otras líneas de aspecto relevante:

Como solución alternativa, cree un script que verifique si openvpn todavía se está ejecutando:
if ! pgrep "openvpn" > /dev/null; then
/usr/sbin/service openvpn restart
echo "["$(date "+%Y-%m-%d %H:%M:%S")"] openvpn restarted">> /var/log/openvpn.log
fi
y llama al script de chat minuciosamente en tu crontab
