Is the problem with domains that you host, or domains that you're 
looking up recursively?

If the latter, it often means that one or more of the authoritative 
servers for the domain they're trying to look up is lame.  BIND doesn't 
try a different server for the domain when it runs into a lame server, 
it just returns a SERVFAIL error.
