Error Message Information Group rad_acct: Radius server <ip address> is responding again (previously dead). Error Group acct: No active radius servers found. Id 106

Explanation This message is seen if the radius-server deadtime 10 command is configured on the access point.This command is configured to set an interval during which the access point does not attempt to use servers that do not respond. Thus avoids the time needed to wait for a request to time out before trying the next configured server. A Radius server marked as dead is skipped by additional requests for the duration of the minutes unless all servers are marked dead. Configuring dead time for 10 minutes means that the server cannot be used for 10 minutes.
