Hola,
Les comento el problema con el que estoy lidiando para ver si alguien puede
darme una mano.
Empezamos a tener problemas con el DHCP en nuestro cluster, de repente
muchas de las instancias dejaron de obtener IP. Este es el log del servidor
DHCP:

Como se ve el puerto correspondiente al DHCP queda en estado BUILD.
En el servidor de DHCP, veo que empieza a sincronizarse hasta que falla con
el error del inicio de este mensaje, desanctiva todos los puertos y
comienza a activarlos y así sucesivamente.
Alguien tuvo algún problema similar, ya se me están acabando las ideas,
agradecería una pista por donde poder buscar la solución.
Gracias!
