PIX losing responses from one particular DMZ website

    We have a PIX 525 running 7.2(2). Recently, without any network
    changes, one particular webserver in the DMZ network became
    unreachable. Other webservers in that same network can be reached as
    normal. In doing packet captures both inside and in the dmz, it looks
    like the page request goes out and the page comes back and gets as far
    as the dmz interface. In packet captures on the inside network, an ACK
    is received from the server for the page request, and that's the last
    thing received on that session. Subsequent attempts seem normal until
    that point, too.

    We have a standby PIX and we've tried doing a failover to that, and
    that device is showing the same behavior.
