Getting huge number of handshake errors when https site is run under heavy load


We have a Gatling scenario where we make 60K students to click on a particular link within 1 to 5 seconds in order to stress test the application. For this we are running Gatling with a cloud-based distribution system, but on execution we see lot of handshake errors (>10K). We are not able to figure out whether the issue is due to client end configuration or the server end. We are not getting much data from our load balancer access logs also on these errors. Can anyone help?


Is the system-under-test configured to handle the connections at that load? Have you tried a ramp-up model to determine at what point you see the failure counts spike?
