I think you need to find out why it is crashing and fix it.  I don't like
using LVS with DNS as DNS balances itself..

I have never been convinced by this argument.

Consider a resolv.conf with IPs:

If is taken offline, then you'll find that the client application's speed at getting domains resolved is drastically reduced because the resolver library will always query before querying

Sticking DNS behind LVS alleviates this.
