Tomcat4.1.17 Apache2.0.43 mod_jk2 Win2K performance

[bg...@clever-age.com]

Hi all,

I've made some benchmark on apache 2.0.43 and Tomcat 4.1.17 using mod_jk2
with jni configuration on win2K plateform.

At 100 users at each time, there is a lot of time out connection and some
times, the connection is lost:
Here are the three kinds of messages I get in my benchmark tool.
-IO failed for VU 1-73 on connection 72/4 with error 258: (Dépassement du
délai d'attente.  ).
-Timeout generated for socket 0x564,
-ERROR 10061: (Aucune connexion n'a pu être établie car l'ordinateur cible
l'a expressément refusée.  ) for VU 1-90 while establishing connection 89/4.,

In the error.log in apache directory, there is errors like this:
[error] lb.service() worker failed 120000 for ajp13:jni
[error] lb.service() uncoverable error
[error] mod_jk.handler() Error connecting to tomcat 120000
...

I hope it is a bad configuration of the connector, when I started apache,
I've got always the same error line in the error.log:
[error] mod_jk child init 1 0
But no error in the stderr.out generate by tomcat.

If you have got an idea to well configure the connector for a better
reliability.

Details of my configuration follows.
Many Thanks for your help.
