loadUI Agent load problems on Linux

Hi All,

I'm trying to setup a load test but facing problems when trying to use more than 3000 concurrent VUs.

Here is what I've done (times 3 as I'm trying to use 3 agents):
Config: [ Intel E5540 with 3GB memory ]
- Installed CentOS 6.3
- Installed loadUI Agent 2.11
- Started the process /opt/SmartBear/loadUI-Agent-2.1.1/loadUI-Agent-2.1.1
- Installed loadUI on a test box
- Used an Existing SoapUI Pro Project and soapUI Pro setting XML
- Added the Agents in loadUI
- Added Ramp UP VU and soapUI Runner

When I configure more than 3000 VUs (i.e. 5000) the process becomes sluggish and the number of Discarded requests start to increase.
I've also tried with only 1 agent and the result is consistent i.e 1 agent will work with 1000 VUs
Ulimit -n and ulimit -a are both over 10000 (both client and Agent)

Observation on the target server:
I can see that the target machine is not receiving the desired number of requests.

Observation on the client (loadUI):
- All 3 machines have a high load
- From shell using top CPU is 100% on the Java process


* Can someone please confirm that my setup is correct?
* What could be the cause of this problem? (tried setting ulimit higher but didn't seem to help)

    Following the update to 2.5.1 the key functionality for distributed testing has been removed, so this question is not relevant. We will use some other tool instead, this is too unstable anyway.
