Hi.
The schema is :
a) request :
browser -(1)-> (apache + mod_jk) --(2)--> tomcat + app.
b) response :
browser <-(1)-- (apache + mod_jk) <--(2)-- tomcat + app.
So let's say that the browser sends the request, over connection (1), to apache.
apache creates connection (2) to tomcat, sends the request, and waits for the
response.
tomcat starts sending the response, which apache reads on connection (2), and starts
forwarding it to the browser over connection (1).
But, for some reason, connection (1) closes (the user closes the browser or the window, or
whatever). Apache would sense that, since it cannot write anymore to connection (1).
And it would (probably) close connection (2) then.
So tomcat, when it tries to send the next response part back to apache, would find a
closed connection (2), and complain.
I don't know if the message below is exactly that case, but maybe it explains why other
people told you that it could be a network problem. It is not a problem directly of
connection (2), but on connection (1), just reflected by apache to connection (2).

For the first time we have received this error (many times). Looks to me
like tomcat cannot talk to apache to me. Can anyone shed any light on
this?
Windows Server 2003
Tomcat: 6.0.16
Apache: 2.2
JDK: 1.6.0_23
Tomcat and Apache on same box so I don't see how it can be a network
issue as some forums are suggesting.
Thanks
