OK. Thanks. Peter.  You've answered what I think I was really trying to get 
clear in my head.  I thought that the two pools,
 
1. the HTTP connector thread pool (governed by the MinThreads and MaxThreads 
parms on the connector in the server.xml in the ../default/jbossweb folder), and
2. the JBoss system thread pool (governed by the MaximumPoolSize attribute of 
the jboss.system:service=ThreadPool mbean definition defined in the 
jboss-service.xml file in the ../default/conf folder)
 
were related.  Reason being, I came across the JBoss Tuning tips at:
 
http://www.mastertheboss.com/en/jboss-application-server/113-jboss-performance-tuning-1.html
 
and there was a comment relating to the HTTP conenctory thread settings that 
said:
 
"if you increase the maxThreads count you need to raise your JBoss Thread pool 
accordingly".  I though that the thread pool being refered to here was the 
JBoss System Threads pool and in my mind this created a dependency between the 
two.
 
I guess the other question I'm asking is:
 
What are all the JBoss thread pools that come into play in order to support the 
needs of the variety of mainstream applications today (assuming its safe to 
frame the question this way!). 
 
The ones I've learnt about so far are:
 
1.JBoss System Threads, attribute "MaximumPoolSize", defined in mBean 
name="jboss.system:service=ThreadPool" of $+server_root+/conf/jboss-service.xml
2.HTTP1.1 Connector Thread Pool, attribute "MaxThreads", defined in the 
<Server><Service><Connector> section of 
$+server_root+/deploy/jbossweb.sar/server.xml
 
What other pools are there?  For each pool that comes to mind, what is the:
 
thread pool name
defined how/where?
what type of processing/tasks it limits/controls ?
relationship with other pools?
 
Any and all comments welcome.
