Is there any way to prevent this? After a few minutes the workerCount decreased for about 50%, which makes it difficult to thoroughly stress-test the server.
Bandwidth can’t be the problem, because I can start several EC2 instances and it doesn’t matter if I start with a workerCount of 50 or 250, the connections will start dropping. The server is \<10% of network usage and the EC2 instances should be able to handle ~100Mbit/s.
Any ideas?
I found a similar thread [here](https://www.wowza.com/forums/showthread.php?16872-Load-test-tool-1%29-drops-connections-and-2%29-does-not-report-this), but it’s more than 2 years old and wasn’t solved…

Hi,
Can you describe where you are running the load test tool? Is this local to you and what is the network bandwidth that you have between the load test instance and the EC2 instance? Simulating 100 clients with an 800kbit/sec stream could saturate a 100mb/sec link.

Hi,
Thanks for the additional information but I think we will need to see both the configuration and log files to troubleshoot this issue. Please create a ticket by emailing support@wowza.com
Include a brief description of the issue, a link to this thread for reference and a zip file containing the following directories:

Hi,
the load test tool runs on m3.xlarge [EC2 instances](http://aws.amazon.com/de/ec2/), which should be capable of handling more than 100Mbit/s. I ran a short test with iperf and between the server and the EC2-instance I reached a throughput of 600 Mbit/s. (with 50 parallel connections)
However, I did also some testing with [flazr](http://flazr.com/) and with this tool I have the same phenomenon:
