Description
We are seeing that in stress tests (positive test, no failures), the clients hang when using DIST mode; both SYNC and ASYNC.
The clients hang in method [1]; there is nothing suspicious on the server side. [2]
The client has no knowledge about repl/dist topology, thus this should be a server-side issue.
As of filing, we are investigating the issue.
