Partial VUsers getting disconnected and getting error as  Connection refused
Kindly guide me with the following problem. I apologize is the same exists on the forum, I tried to explore but was unable to find the solution.
I have an application server (JBoss) which connects to a database (PostGres) and follows HTTP protocol.
I'm trying to test the performance by running concurrent users through LoadRunner.
For a load of say 300 users, around 190 gets through the run while for the balance an error is shown as "Failed to connect xxx.xxx.xxx.xxx:xxxx.  Connection refused".
This count varies with each run. I've increased the Step-Download & Keep-Alive value also in Run-Time settings to offset any delay during the run. My entire environment is on LAN.
