SwingBench 2.6 : Connection reset by peer- Authentication lapse 0ms is seen when using more than 2 users

[mbadayil]

Hi,

I'm running some benchmark testing with SwingBench version 2.6 against Oracle 19c. My plan is to run with 100 users, however after 2 or3 users I started getting Connection reset by peer- Authentication lapse 0ms error, I tried this many times and all the time I'm hitting same error. Any help would be appreciated! Please take a look at the screenshot, if you need more info please let me know

Here is the error-stack :
