Subject Client TCP Connections go to FIN state after each request
Date Fri, 09 Nov 2007 19:40:45 GMT
Hi
I am trying to upgrade from apache 2.2.4 to 2.2.6 on Red Hat AS4
update4-x64  configuration

I compiled apache with following options. My 2.2.4 apache was also
compiled with below configuration. 

./configure --enable-proxy --enable-proxy-http --enable-proxy-connect
--enable-proxy-ftp --enable-http-core --enable-rewrite --enable-ssl
--enable-deflate --enable-expires --enable-so --enable-headers
--enable-logio --with-ssl=/cust/openssl-0.9.8f
--prefix=/usr/opt/apache2 --with-mpm=prefork --enable-maintainer-mode


I connected 2.2.6 using the httpd.conf file which I was using in 2.2.4.

I collected tcpdump { tcpdump -s 0 host webServ -w dump.log } on one of
the servers where apache was proxypassing requests.
On analysing with etheral I observe that apache is closing the
connection after every request.
Here is a section from etheral which keeps repeating after every
request->

Header
"No","time","Source","destination","protocol","Info logicalport >
listening port [Status]...... "

Data ->
"3","0.018626","208.246.226.171","208.246.226.166","TCP","33164 > 9380
[FIN, ACK] Seq=0 Ack=1379 Win=17 Len=0 TSV=380276575 TSER=327971424"

Then next request starts from next port ->
"4","0.018668","208.246.226.171","208.246.226.166","TCP","33165 > 9380
[SYN] Seq=0 Len=0 MSS=1460 TSV=380276575 TSER=0 WS=9"


This problem is not there when I connect with 2.2.4 to the same server.

I read the release notes, googled etc.. but could not find a clue. 
Any clues where to look for?
