    Description

      Problem:
      There is an upstream bug in Netty whereby the maxCapacity parameter for the Recycler is not honored under certain usage patterns with the Java SDK. The result is a slow, but gradual memory leak. It has also been observed that the hardcoded default value of 262144 is not honored within Netty as well.

      A current workaround is to set the maxCapacity parameter to 0 and disable the Recycler:

      -Dcom.couchbase.client.deps.io.netty.recycler.maxCapacity=0

      Request:
      As the Couchbase Java SDK leverages Netty, we should find a way to help resolve this issue in Netty.
