DHCP Scope randomly stops handing out IP addresses

Hello,

I have a VM running only DHCP that is part of a cluster, and in the past few months it's decided to stop handing out IP leases at random. When you try to restart the services sometimes they hang, other times it works. We have found we can disable our VoIP DHCP scope which resides on the same server and the other scope starts handing out addresses again. These two scopes have been on the same server for the past year though with no issues until now, and no changes have been made to either the scopes, VM, or the phone system.

Checking the event log on the VM, the only errors we see are the VoIP scope having alerts that it's low on IP addresses, but nothing else. Checking the Host that the VM resides on doesn't show any errors in the event log either.

Does anyone have any suggestions where I could check to see what the issue is?

Thanks
