confused about System Threads Pool

[jtcnz]

Using web-console, look at jboss.system:service=ThreadPool
The attributes metrics:
QueueSize 0
BlockingMode Run
MinPoolSize 10
MaxPoolSize 10
MaxQueueSize 1000

Then look at jboss.system:type=ServerInfo
ActiveThreadCount 141


The size of ThreadPool is 10. Why are there 141 threads active?

[peterj]

Because the ThreadPool has nothing to do with the HTTP threads - those are two different pools controlled by two different settings.

[peterj]

And in addition there are many threads not in either of those pools. For example, the JVM itself runs several threads which are included in the ActiveThreadCount.

Hi Peter,

where can I config the HTTP thread pool size?

Should be this "name=http-0.0.0.0-8080,type=ThreadPool" from jmx-console, but I can't find where can I config it

Jboss 4.2.3 & Jboss 5.1.2

[bondchan921]

by  <Connector protocol="HTTP/1.1" port="8080" address="${jboss.bind.address}"

               connectionTimeout="20000" redirectPort="8443" /> in server\default\deploy\jboss-web.deployer\server.xml ?

and the default of maxThreads is 1024 ?

Yes, you configure the HTTP thread pool size using server.xml. You can use the Tomcat 6 documentation to determine what to set and what the defaults are.
