SocketException after upgrading to C# driver v3.2.0

After upgrading to C# driver v3.2.0 from v3.1.0, we’ve started to receive the following exceptions as UnobservedTaskExceptions in Sentry. I cannot reproduce them while running locally in a Docker container but they do occur when running in AWS ECS. I do not see any unawaited tasks. System does not appear to be negatively affected. Kind of at a loss where to go from here. Any advice?

System.Net.Sockets.SocketException: Operation canceled
  File "Socket.Tasks.cs", line 1386, in void AwaitableSocketAsyncEventArgs.ThrowException(SocketError error, CancellationToken cancellationToken)
    throw CreateException(error, forAsyncThrow: false);
  File "ValueTask.cs", line 258, in void ValueTaskSourceAsTask.s_completionAction(object state)
    source.GetResult(vtst._token);
