-----------------------------------
Moved to AS7 project JIRA for now since I'm not yet sure it's got to do with EJB client or remote-naming project.
Can you post the code in the RemoteClientAPI class?
> Load testing application with Jmeter & jboss remoting throws exception saying "Too many channels open"

> I've created a sampler for JMeter for load testing application. When I ran that with say around 30 threads with rampup time 80 seconds, after a while I kept getting exception specified in https://community.jboss.org/thread/195709?tstart=0. I later tried to close InitialContext in teardown methods, but wasn't really helpful. I looked at no. of InitialContext intances present in the VM using visualvm heapdump & found that just before throwing exception, it was 24 & after throwing exception for all threads, it did reach to 30, but it wasn't useful..
> Please note that, I'm creating InitialContext with passing following parameters to it:
> java.naming.factory.url.pkgs=org.jboss.ejb.client.naming
> java.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactory
> java.naming.provider.url=remote://localhost:4447
> jboss.naming.client.ejb.context=true
