It seems the problem is local to your web application.

Create a test JSP in your web app, and try accessing it.
If it isn't responding, maybe all the available Thread for your web app are used,
maybe you have a dead lock somewhere...

I think that the number of threads available is specific to your Connector :

 <Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
         port="8080" minProcessors="20" maxProcessors="400"
         enableLookups="true" redirectPort="8443"
         acceptCount="100" debug="0" connectionTimeout="20000"
         useURIValidationHack="false" disableUploadTimeout="true" />

try increasing it... (default is min=5 max=75)

Thank you very much Raymond.
However all memories you pointed out are enough.
CPU load is almost zero.
During this problem is happenning, I create another small
test application and run. And I could get the result that
"Tomcat is running properly".
What's happen???
I think only my original application just hung up.
No error messages. No warnnings. No logs.
To recover this problem, is to reboot Tomcat.

Any suggestion would be appreciated.

George
