Selenium Browser keeps dying on me - selenium

Question

I see other people have been having this issue, by mine seems a bit different than anyone elses as it only is occuring when I run a full suite (fails on like test 20).
if I run a single test or only a few test, the code works just fine.
Otherwise, I get the following stack trace:
org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser. It may have died.
I am running my code locally and I don't know why it doesn't try to create a new browser. Instead, it just skips all the remaining cucumber steps.
Does anyone know why this would happen?
Here is my setup and teardown steps:
public class Setup_Teardown_steps extends BaseStepClass {
#Before("#selenium")
public void selenium_before_step(Scenario scenario) { //Function responsible for setting the scenario start and global end condition
//Selenium setup
//initialize_selenium_elements();
driver = WebDriver_Singleton.getNewDriver(); //Creates a new Webdriver instance.
driver.manage().window().setSize(new Dimension(1280, 800));
startTime = System.currentTimeMillis();
testData.ClearTestData(); //Clears saved test data
testData.current_scenario = scenario;
}
/**
* After each scenario Hook (except report scenarios) - public cause it has to be.
*/
#After("#selenium")
public void selenium_after_step(Scenario scenario) throws IOException {
endTime = System.currentTimeMillis();
scenario.write("Run time = " + (endTime - startTime)/1000 + " seconds");
if (scenario.isFailed()){
String html_link = driver.getCurrentUrl();
scenario.write("\n");
scenario.write("URL = " + html_link);
try {
byte[] screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.BYTES);
scenario.embed(screenshot, "image/png");
} catch (WebDriverException wde) {
System.err.println(wde.getMessage());
} catch (ClassCastException cce) {
cce.printStackTrace();
}
}
driver.close(); //Clears cache and cookies
testData.ClearTestData(); //Clears saved test data
}
}
//WebDriver_Singleton Function below
private static WebDriver create_driver(){
if (driver != null){
driver.close();
}
assign_base_urls();
String browser = System.getProperty("browser") == null ? "ff" : System.getProperty("browser");
switch(browser.toLowerCase()){
case "ff":
case "firefox":
case "mozilla":
driver = new FirefoxDriver();
break;
case "ie":
case "internet explorer":
case "internet_explorer":
driver = new InternetExplorerDriver();
break;
case "chrome":
case "google":
driver = new ChromeDriver();
break;
default:
System.out.println("Defaulting to Firefox browser");
driver = new FirefoxDriver();
}
driver.manage().timeouts().implicitlyWait(implicit_wait_timeouts, TimeUnit.SECONDS);
driver.manage().timeouts().pageLoadTimeout(page_load_timeouts, TimeUnit.SECONDS);
driver.manage().timeouts().setScriptTimeout(script_timeouts, TimeUnit.SECONDS);
return driver;
}

I looked at the stack trace, was hard to find but the jenkins server was running out of memory.
