    Urgent Help Regarding Stateless Session Bean

    Kumar Jaya Newbie

      I am using EJB3 in JBoss 4.2.2. My standard-jboss.xml has the following standard configuration

      <container-pool-conf>
      100
      </container-pool-conf>

      for <container-name>Standard Stateless SessionBean</container-name>. I have as many as 7 Stateless Session Bean in my ear, one (Ex: SLSB-AA) of which is called remotely and others are called locally. I am calling the SLSB-AA as many as 70 times per second and there are local calls between SLSBs. My code outside JBoss which calls the SDSB-A run perfectly for 700 to 800 calls. After when I get the exception

      I increased the pool size
      <container-pool-conf>
      1000
      </container-pool-conf>

      even then I get this exception after calling my SLSB-A for 1200-1300 times. Any help is greatly appreciated
