아래 참고 링크를 참고하여 윈도우 레지스트리 값을 수정하였다.
Win+R regedit 입력
컴퓨터\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
경로의 MaxUserPort 값 우클릭 > 수정 후 10진후에 체크한 뒤 65534 로 수정
이후 해당 에러는 발생하지 않았지만 application 의 connection pool 이 문제인지 일정한 tps 가 나오질 않네...
참고 :

Solved "java.net.BindException: Address already in use: connect" issue on Windows - BASE Logic, Inc.
