httpd immediately closes connection in -current/i386

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

I recently updated a machine from 5.1_RC3 to -current (chasing video
card support, which is improved, thankfully).

As a side effect 'httpd' (the in-tree bozohttpd) stopped working.  Even
after picking up the latest import, it behaves as follows:

With Firefox:

  browser initiates connection with SYN
  httpd responds with SYN,ACK
  browser completes handshake with ACK
  browser sends HTTP GET
  httpd sends FIN to begin tearing down connection
  browser sends FIN,ACK
  httpd sends ACK
  browser sends ACK

With lynx:

  browser initiates connection with SYN
  httpd responds with SYN,ACK
  browser completes handshake with ACK
  httpd sends FIN to begin tearing down connection
  browser sends ACK
  browser sends HTTP GET
  httpd sends RST to drop connection
  (above operation repeats once more)

httpd is running as follows:

  /usr/libexec/httpd -u -V -v /home/_httpd/vhosts -U _httpd -b /home/_httpd

where "/home" is handled by 'amd' making "/home/_httpd" a link to
"/d0/home/_httpd" which is a local filesystem.

This worked with no problem under "netbsd-5".  Is anyone else seeing
anything like this?  Can I get more visibility into the problem without
running it under a debugger?

Thanks.
