Subject [jira] Commented: (GERONIMO-5157) Tomcat 6.0.20 NIO connector cause connection always terminates in a very short time interval

    [ https://issues.apache.org/jira/browse/GERONIMO-5157?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12841368#action_12841368

Ashish Jain commented on GERONIMO-5157:
---------------------------------------

I was able to increase the performance of the stock quotes refresh and now I see very frequent
updates. For this I have modifed some part of the  web messaging code. However I still see
that there are requests with empty responses. Also I see cpu usage going up. 

Further I see that in tomcat the processing being done by HTTP11NioProcessor.event has been
moved to HTTP11NioProcessor.process in 6.0.20. I am still looking into this issue. Since this
is multithreaded I am finding some difficulty in getting to the actual cause. Any suggestions
on how to debug effectively will be really helpful.

> Hi,
> I have a sample application which uses the Web messaging service tosimulate stock quotes
to a Dojo-enabled client application and i use Tomcat NIO connector for comet support. I tried
deploying the application in G2.1.5-snapshot  the stock quotes update doesn't happen properly
but it works very well in G2.1.4. A look at the requests inthe firebug shows that the bayeux
connection always terminates in a very
> short time interval. however, I don't see any exceptions or errors in the console.
