Subject: java.rmi.ConnectException: Connection refused to host


Hi,

I am trying to call 1 method on a SLSB remotely.
I am running the method call in a thread which are being created
In a loop.

BASIC idea is to simulate 50 Users concurrently accessing

If I create 40 threads then everything goes fine. But, the moment
I cross 45, I start getting this error:

java.rmi.ConnectException: Connection refused to host: 192.168.146.134;
nested exception is:

If I call home.create() in run then I get this error at retry = 15-20.
