Once initialization is complete, the main thread does nothing but listen for

It's not the number of waiting threads, it's the number of times this
particular thread has done a wait() call. Since the main thread i

is there any defining characteristic which causes these threads to sit and wait?
maybe a DB Connection or calling a remote resource that is causing the block?

What tool do you use to perform requests? Regular web browser?
Try with something more 'generic' - wget or ab.

No, single-thread is not the default.

There's no way I could be doing any such thing unknowingly, such as it

Hi
If you are on linux, do the following:
killall -3 java
Then look into catalina.out.
It will print all stack traces, including monitors being hold and waited for.

Tomcat version?
Java version?
Anything in the servlet that synchronises on a common lock?
In general, one worker thread handles one request, from start to finish; then
it's returned to the pool to be reused. Is that what you would expect?

Hello Frederic,
unless you are using the SingleThreaded Model (and you shouldn't)
tomcat does no such thing.
I assume the best way is to show us your servlet code, or to check for
synchronized blocks in it.

Well, it might be possible to design an applet that pulled someone's
public IP (maybe by polling your site directly? Have to make sure not
local IP) then cross that against the request origin into Tomcat; if
they don't match then that could be construed as a Proxy situation. I

I'm trying to block external access to port 8009 (AJP13), as only my local host

iptables is the best option.
If anyone has iptables rules that work, I'd appreciate i
Try adding address="127.0.0.1" to the ajp13 tag in server.xml,
and configuring apache to connect to 127.0.0.1 if you haven't already.
This should stop the ajp13 port from being visable to other machines.
As far as iptables goes, you probably want -o lo -j ACCEPT at the top of the
