STOP SENDING HTTP REQUEST

Hi,
   
  I have a  problem with jMeter 2.2. I'm trying to overload an apache server on my local network. I'm using 6 computers as a remote jmeter-server and another one to get the results 
   
  The test plan looks like:
  One thread group with 12 threads with a ramp period of 6000 and loop count of 6000
          Simple Controller
                 Cookie Manager
                7 HTTP Request (one of them using HTTP User Parameter Modifier)
            Aggregate graph.
  
Jmeter is supposed to send 12 * 6 (computers) * 6000 (iterations) = 288000 requests.
  Jmeter stop sendigs requests when it gets 12 000 request with no reason. This number is aprox because I ran the test many times and I get an interval from 9000 to 15000 requests   There are no messages in the log files of each computer. I kept my test runing the whole night and the day after nothing had happened.
   
  I can see that requests dont get the apache server and if I send the same request from one of the remote server in the browser I get response.
   
  If  I observe the Aggregate graph  I can notice that the rate of sending request decrease progressively.
   
  Thank you for your help

That might have the effect of overloading the client computer and its
network connection....

Aggregate Graph is very resource intensive.

See
http://jakarta.apache.org/jmeter/usermanual/component_reference.html#listeners

Summary Report would be cheaper.

First try using Summary Report instead of Aggregate Report, as this is easiest.

If that does not help, then run the test on each node in non-GUI mode,
using CSV output, and then combine the results for further analysis if
required.

Make sure the clocks of all the hosts are reasonably well synchronised.
