Describe the bug

Reference issue - #13763

Intermittently receiving LEAK errors like [ERROR] LEAK: ByteBuf.release() was not called before it's garbage-collected. when using ResourceLeakDetector.setLevel(ResourceLeakDetector.Level.PARANOID)

This is happening for my local Mac machine and an Azure VM in the US east 2 region. While somehow it doesn't happen when running the same code from an Azure VM in the US west region.

Exception or Stack Trace
[ERROR] LEAK: ByteBuf.release() was not called before it's garbage-collected. See https://netty.io/wiki/reference-counted-objects.html for more information.

To Reproduce
Steps to reproduce the behavior:

  1. Create an Azure VM in East US 2 with Linux.
  2. Install docker
  3. Use the code from above referenced issue - https://github.com/tysonnorris/azure-cosmos-java-getting-started/tree/netty_leakdetector
  4. Build the docker image -> docker build -t cosmos-sdk-leak:latest .
  5. docker run -e ACCOUNT_HOST='YOUR_ACCOUNT_HOST' -e ACCOUNT_KEY='YOUR_ACCOUNT_KEY' -it cosmos-sdk-leak

Normally the exception arrives within 5-10 runs (runtest.sh executes a while loop)

Observation :

  1. performed the above steps from my local Macbook and able to reproduce.
  2. performed the above steps from Azure VM in West region and not able to reproduce. (However my region of interest is US East 2, but did test via West also to compare behavior)

Code Snippet

https://github.com/tysonnorris/azure-cosmos-java-getting-started/blob/netty_leakdetector/src/main/java/com/azure/cosmos/sample/async/AsyncMainLeak.java is a modified version of the AsyncMain.java sample

Expected behavior
No Exception should occur
