When we are closing the spring boot(3.3.0) application then showing Unexpected exception occurred invoking async method in the log repeated many times. We have used the Spring Scheduler for processing the file.

That issue is coming only Linux machine, on windows machine working fine.

Scheduler configuration

schedulers.thread-pool-size=50
timeout.time-in-minutes=2
schedulers.time-in-milliseconds=10
