I have a Zimbra server where eth0 is assigned two IP addresses. I want to phase out the use of one of these addresses. In /etc/hosts, the address I want to get rid of is defined. I changed this line to the other address assigned to eth0 and got the following in /var/log/messages:
zimbramon: 13436:info: zmmtaconfig: Sleeping...Key lookup failed.
Changing /etc/hosts back immediately fixed the problem.
Do I have to restart Zimbra in this situation? Is there anything else that would need to be changed. Our DNS configuration uses the IP address I want to keep, so that shouldn't be a problem.
