Hello,
First, you'd better keep JBoss specific questions out of EJB-interest and
redirect them to JBoss forums.
As for your problem, I suspect this is either the OS or the server socket
that refuse to queue/handle so many concurrent connections. You may want
either to check with your TCP stack configuration or, at the JBoss level,
increase the value of the Backlog (change the JRMPInvoker MBean "Backlog"
attribute in file JBOSS_HOME/server/default/conf/jboss-service.xml)
BTW, are you sure it is JBoss 3.0.3? 3.0.3 was the first release to have a
default backlog setting of 200 (and thus override the default JDK value of
50 that could explain your behaviour).
Cheers,
Sacha
