Can you post "connectors" part of your Tomcat's server.xml and your
workers.properties?

Just to add to this, I'm also getting the following error in tomcat
connector's mod_jk.log

 Subject: Apache/Tomcat request hangs intermittently



We have a webserver with Apache 2.2.2 running that acts as a pass-thru,
forwarding all  POST requests from the internet to Tomcat.

The connection works but sometimes, a request on the webserver just hangs.
If I re-try a few times, the webpage eventually opens.  I'm not quite sure
what is causing this.  If I bounce Apache, it works normally for a few hours
and the problem starts again.  For  Debug Loglevel, I get the following
errors in error_log.  I'm not quite sure if this has anything to do with my
problem –

When I do a netstat –a on the webserver, I see that the connection has been
established, but my browser just keeps spinning and spinning.



tcp        0      0 *:8000                      *:*
LISTEN

tcp        0      0 <webserver>:8000 ::ffff:<mylocalIP>:1757    ESTABLISHED



This is our Production website.  Can someone please help me out?



Thanks very much.
