Has anyone seen/resolved a split brain recovery in Unity Connection 10.5.2? The primary and secondary keep swapping back and forth every few minutes. I can ping and trace to each server. I restarted the primary but that did not resolve the issue. In the
RTMT system logs, the secondary sends an NTP query to the primary the response is the primary is inaccessible or down. I'm stumped.</span><o:p></o:p></p>
