Subject:	Please help for a query in Tomcat. - Problem : Tomcat gets hanged

Hi,

We have designed an application which works in Java JSP - Tomcat - Oracle
environment.

Our JSP page has two frames.
1). First frame : This is the top frame containing links (displayed as Tabs)
2). Second Frame : This is below the top frame and is updated with the
selected link.

For each click on the link a request is submitted and the response is
populated in the second frame.
The second frame contains a search criteria and fetches data from the
database.

Conditions when Tomcat hangs
1). When we try clicking on the links very fast
2). While the data is being fetched from the database and manipulated and if
we click on other the links the server gets hang.

Our analysis and understanding is :
There would be some threads (requests) whose output was not allowed to be
displayed in the second frame due to click on other links which would spawn
another request for the same target.
These requests remain in "Service" state as understood from the
Tomcat-Manager status.
Also, as per the information given on the link
http://forum.java.sun.com/thread.jspa?threadID=454684&messageID=2072194
these requests would "always" remain in Service State.

Please confirm whether our understanding is correct.
Please provide a solution to this problem? Let us know in case any further
information is needed.

Thanks and regards,
Reshma
