Answer 1

Though your server has 16 GB RAM, JMeter's default heap size 512 MB, Increase heap size by following below steps

1. Open jmeter file using vi editor /text editor
2. Search for "HEAP"
3. Change minimum (-Xms) and Maximum (-Xmx) heap values as you required
4. Save and quit (!wq enter)  
5. Start Jmeter by sh jmeter.sh or bash jmeter.bat or java -jar ApacheJMeter.jar
