This means that your F5 is sending to much RST-Response because someone tried to access a non-existing service port on your F5.
Err Msg: 011e0001:4: Limiting open port RST response from 501 to 500 packets/sec (f5.com)
The only explanation for this would be, that your Pool got marked down so that your VS will be marked down too and your test still tries to access your VS (causing the system to send reset responses).
Can you please verify if your pool became unhealthy during your tests?

Sorry...
The log lines you send where complaining about "Limiting open port RST" and not "Limiting closed port RST" (both messages exist)
The "Limiting open port RST" happens if the F5 receives a "Non-SYN" packet on a open port, but does not have a related connection for it. This may happen with legitimate traffic if network issues interrupting bidirectional communication...
Heath_Parrott pointed out "Connection Table" limits in AWS. Those may be a good explanation for the interrupted communication you see in your logs. Did you already clarified with AWS?
