Ok, you're hitting a limit in your API server's workload. This is what you're using jmeter to find. It may be that no other apps are putting as much of a load as you are with jmeter. You need to tune your load test according to your needs. You need to have some kind of metric that you are trying to hit. So in short the issue is not JMeter. JMeter can generate a lot of load and can easily overwhelm a server with requests.
