[Pound Mailing List] FreeBSD and failed requests

     A rather strange problem I'm having.  Searching through the  
archives I see this exact question was asked back in February but got  
no responses.  The issue is that the throughput by a server running  
Pound falls flat, and generates failed requests on the magnitude of  
70-80% by Apache bench, even when performing a request as small as 50  
with 1 concurrent user.  If I bypass Pound and direct the requests  
straight to the back end web server, failed requests drop to zero.   
Necessary background info would be that the OS is FreeBSD 6.1-RC2,  
that I get this problem with pound 1.9 out of ports, and that it  
persists even with 2.0.4 built against a separate OpenSSL with  
threading enabled.  Since I'd prefer to use 2.x, here's the current  
config:

User "www"
Group "www"
LogLevel 2

ListenHTTP
  Address 10.10.10.32
  Port    8080
End

   Service
      BackEnd
          Address 10.10.10.35
          Port    80
      End
      BackEnd
          Address 10.10.10.36
          Port    80
      End
   End

     Of note is that despite LogLevel 2, no complaints are showing  
up in /var/log/messages.  It logs the startup notification and  
nothing else so I don't have anything useful to include from that at  
the moment.  Here's some ab info to illustrate what's going on:
