Wow. I've seen slow DNS before, but typically it is due to my  
application not calling ::process() in a timely fashion in the stack.  
Are you running HEAD from SVN or something else?  The general idea in  
reSIProcate is to always query the DNS, or use a cache. Later  
versions of reSIProcate from SVN include a local caching nameserver  
to assist with SRV server migration.

So, I guess you should:

	a) check that you are calling process sufficiently.
	b) let us know what reSIProcate codebase you are seeing this in.
