We're continuing with this issue and I'm not even certain if it is an
issue. Our linux box (sles 9 or sles 10) opens a connection to the
mainframe (we have tcp offloading turned on since we turned it off and
it didn't change the issue), they talk, then the linux side sends a http
200 and immediately a FIN ACK before the mainframe can send anything.
This is causing exceptions on the mainframe side.

By the way, if it really is causing exceptions, then your application is
simply badly programmed. KeepAlive is just a performance hack. In principle,
HTTP is a stateless protocol that requires a new connection for each request.
The fact that this can be sidestepped by using keepalive means things can be
speeded up, but the client should still be able to handle opening a new
connection
