No response to status-server but radtest status ok

Hi, On our eduroam FR proxy, we had a home_server in a dead state for several hours. All status-server requests sent seemed to go unanswered. During this period, I checked this home_server status with radtest : got answers ! I tried to get this host alive by radmin: it fell back to zombie and dead states again. The only solution found to revive this home_server : restart the FR process on our proxy and the home_server remain to alive state. So, here are my questions : - Why the status-server requests sent by FR in dead state did not get answered, while those sent by radtest get response ? - Is there a way to force a revive from a dead state even with unanswered status-server requests ?
