   @chrisdutz I have tried the revision tagged with 
[v0.11.0](https://github.com/apache/plc4x/releases/tag/v0.11.0), but the 
problem does not seem to be resolved yet. :(
   
   ```
   ~/plc4x$ git log -1
   commit d22042ef079ae93120770a95704571118d9c871e (HEAD, tag: v0.11.0)
   Author: Christofer Dutz <cd...@apache.org>

       [maven-release-plugin] prepare release v0.11.0
   ```
   
   As you can see on the screenshot below, the heap usage is still constantly 
increasing:

   Tested with the following code:
   ```java
   public class MemoryLeakDemo {
   
       public static void main(String[] args) throws Exception {
           PlcDriverManager driverManager = new DefaultPlcDriverManager();
           PlcConnectionManager connectionManager = 
driverManager.getConnectionManager();
   
           AtomicBoolean running = new AtomicBoolean(true);
           Runtime.getRuntime().addShutdownHook(new Thread(() -> 
running.set(true)));
   
           while (running.get()) {
               PlcConnection connection = 
connectionManager.getConnection("opcua:tcp://127.0.0.1:12686/milo?discovery=false");
               try {
                   Thread.sleep(100);
               } finally {
                   connection.close();
               }
           }
       }
   }
   ```
