HUge Number of Request Causes RunOutOfMemory

[nicholaswkc34]

Dear forumers, I tried to code 1 million users request on homepage but it has run out of memory,

public class orangehrm extends Simulation{

    // Add the HttpProtocolBuilder:
    HttpProtocolBuilder httpProtocol =
            http.baseUrl("https://opensource-demo.orangehrmlive.com/web/index.php/auth/login")
                    .acceptHeader("application/json")
                    .contentTypeHeader("application/json");


    // Add the ScenarioBuilder:
    ScenarioBuilder homepageScenario = scenario("Homepage Street Testing Scenario")
            .exec(http("Homepage Request").get("/"));


    {
        setUp(
                homepageScenario.injectOpen(constantUsersPerSec(100000).during(3600))
        ).protocols(httpProtocol);
    }
}

Errors;
