We have been having this issue for a while. Meraki has not provided a solution. Our MX device stops responding to DHCP requests. The pool is nowhere near maxed out. We have downgraded and replaced the MX, but nothing helps. We checked the device utilization to see if it was working too hard but it's only at 25%. We can't figure out why the DHCP function just stops. The only fix has been to reboot the firewall to start DHCP backup.
