Re: [Pound Mailing List] FreeBSD and failed requests

You say something about being out of ports with 1.9.  That seems 
impossible if you are sending 50 requests with no request concurrency.

What do the server logs say when you are using pound?

Also, what kind of transactions are these?  Is there a possibility that 
pound is rejecting many of them as ill-formed?
