No, it isn't reasonable to expect a restart of server "B", because someone 
changed some data on server "A".

Yes, you do.  DNS is dynamic.  It changes.  But information is cached locally, 
so the DNS requests rarely go futher than your local machine.

>If not, what is a reasonable cache lifetime for the lookup?
The local DNS resolver will cache for you, based on the time-to-live value 
returned by the DNS server.
