[DongSeungLee]

Describe the bug
Please provide details of the problem, including the version of Spring Cloud that you
are using.
My development environment is like below.
spring boot 2.5.13
spring boot starter consul discovery 3.0.4
spring boot starter gateway 3.0.6

i have customHealthIndicator implementing ReactiveHealthIndicator, thus, i always health down before shutdown my application.
sometimes, after health down, around 30s elapsed, i kill -15 pid(my application pid), errors are printed like below.
