Poor Forms performance - application.log errors

Question

Hi
We have an environment that is supporting over 3000 users. The application servers are Win2K using Forms 10.1.2.3.0.
Users are constantly experiencing poor performance, taking an age to switch from one form to another.
Ignoring all the other possibilities like network etc the only information I can find is in the $ORACLE_HOME\j2ee\applications-deployments\formsapp\OC4J_BI_Forms_default_island_1\application.log
The following is a typical error message:
java.net.SocketException: Connection reset by peer: socket write error
     at java.net.SocketOutputStream.socketWrite0(Native Method)
     at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92)
     at java.net.SocketOutputStream.write(SocketOutputStream.java:136)

     at java.lang.Thread.run(Thread.java:534)
The following config details are important:
1. httpd.conf - ThreadsPerChild=150 MaxRequestsPerChild=0
2. formsweb.cfg - heartBeat=2 FORMS_TIMEOUT=15
Has anyone come across a similar situation? Does this error message suggest any Oracle configuration issues I could look at?
Regards
Andy

I don't see that parameter.
Here is my web.zml file:
