[jboss-user] [Remoting] - java.net.SocketException: Can not obtain client socket conne

[kapil.singhal]

Hello,

I am having JBoss 4.2.2 GA, PostgrsSQL 8.2 and Jboss Remoting version  2.2.2 SP1.

I want to connect 64 clients to the JBoss Server but after creating 50 sessions / connections, it is giving the exception on the Client side.

The exception is as follows:

I have gone thru various tutorials but not able to manage more than 50 connections.

I have modified the jboss-service.xml also for <max-pool-size> and , but it is still stuck to 50 connections.

Please reply asap.
Any help will be appreciated.

Thanks & Regards,
Kapil
