Zimbra fail to recover when DNS goes down

[riyazna]

Hi ,

In my organization around 2000 users are using a multi server installation setup of ZCS 7.1.3. We observed one thing with zimbra, when ever the DNS response is slow, Zimbra goes down and not responding . That's ok , we can understand.

But Zimbra continues to work slugginsh and Throw java exception error , even after the DNS got recovered. a restart of Zimbra application is required for Zimbra to recover and start working.

It doesn't slow down in my environment even if I take both of my DNS servers offline, it recovers when they become available. Don't you have multiple DNS servers available on your LAN? Why does the DNS response become slow?
