Hello Tomcat users,
We are having difficulty with connections to Tomcat remaining open
after the client hits "stop" in their browser.
This only seems to happen when we have a particular combination of
load balancer hardware in front of the tomcats. We are also running
apache and have not seen the same behavior there, even though the
load balancer hardware and config is the same.
We are using Tomcat 5.5.20 on linux 2.6.9-34.0.1.ELsmp. It is
running standalone. We are using APR in some environments and not
in others, but see the problem in either configuration.
We have captured tcpdumps and see the pattern at the bottom of this
email. It appears that the web application tries to retransmit until
it gets a RST from the client after about 12 minutes. When we finally
get the RST, we get a lot of exceptions (some of them are due to the
fact that our session timeout is shorter than the length of these
requests. I can add them later if they would be useful).
When we do threaddumps of the java process, many threads appear to
be stuck in java.net.SocketOutputStream.socketWrite0
Thread [0x00000fd] exceeded timeout of [180000] millis. Current
execution stack

I have done some research, but I'm not finding a cut and dried answer
to this issue. It seems that the RST behavior of browsers has been
noted before:
http://pages.cpsc.ucalgary.ca/~carey/papers/2005/TCP-Resets.pdf
It seems like the main difference between having the load balancers
or not is the timing of when we get the RST.
Some questions:
Is there anything that can be done on the tomcat side to protect itself?
Why does it not send a FIN back when it gets a FIN from the client?
Why would it be different for Apache?
Thanks,
-Mike Roark
Notes on this output. Our application runs on port 8585. The client
sends
a FIN at packet#33. The web app begins retransmitting at packet#36.
