      Use Thread Pooling configuration from server.xml which resides in \jboss-5.1.0.GA\server\default\deploy\jbossweb.sar

      <Connector protocol="HTTP/1.1" port="8080" address="${jboss.bind.address}"
      connectionTimeout="20000" redirectPort="8443" maxThreads="1000" />

      1) Start JBoss 5.0.1GA server with below VM parameters.
      -Xms1024m -Xmx1024m -XX:MaxPermSize=256m
      2) Open web-console.
      Goto JBoss-web -> jboss.web.type=ThreadPool, name=http*-8080
      3) Assign the value of maxThreads=1000 and apply changes.
      4) Fire concurrent threads more than 200, We are using Grinder tool as a part of load testing.
      5) Open graph for "currentThreadBusy", and observe the behavior of busy threads.
      5) After few minutes (totalthreads - 200) gets busy and will never gets free.

    Description

      When we fire concurrent request more than 200, let's say 200+x (With maxThreads specified 1000 from jmx/web console), Everything works fine but after few seconds x NUMBER OF THREADS GETS BUSY and they never get free. On server log we are getting below ArrayIndexOutOfBoundsException.
