java.io.IOException: java.lang.IllegalStateException: Connection pool shut down

Hi!

I am using Pinot and have this famous issue coming after exactly one hour on Pinot cluster running on EKS. I have explained the issue in detail here

To summarize, Pinot is using IRSA role to access S3. It works for an hour after which I am getting this error.
The code for pinot-s3 is here

It started happening after upgrading awssdk from 2.14.28 to 2.20.94

We are unable to figure out why this issue is happening. It would be great if I can get any tip why it is happening.

So far, I have checked that there are no OutOfMemoryErrors and I have also set maxConnections to 500 but it didn't resolve the issue.,
