MAAS 2.9.2 (snap). Was working ok until memory and disk got exhausted. I fixed those problems but after rebooting the DHCP services are not starting.
~$ sudo maas status
bind9 RUNNING pid 1138, uptime 0:11:56
dhcpd STOPPED Not started
dhcpd6 STOPPED Not started
http RUNNING pid 1443, uptime 0:11:39
ntp RUNNING pid 1256, uptime 0:11:52
proxy RUNNING pid 1418, uptime 0:11:41
rackd RUNNING pid 1141, uptime 0:11:56
regiond RUNNING pid 1142, uptime 0:11:56
syslog RUNNING pid 1258, uptime 0:11:52
Any suggestions please?
