SSHClient: ForwardedPortLocal: memory issue

Comienza con el punto de entrada ConnectSSH y la creación repetida de ForwardedPortLocal que se muestra en el informe. Reproduce el escenario durante toda la noche o con llamadas repetidas y, a continuación, sigue el ciclo de vida del reenvío de puertos y el comportamiento de liberación; se considera terminado cuando las conexiones repetidas ya no muestran un uso de memoria que aumente de forma constante.

Hello,

I am using the following code below. I call this ConnectSSH() every 5 seconds (as a test to see how it performs)
After I let this run a night, i see that the used memory increased significantly, and it keeps rising.

After some investigation on my own, i notice that when I remove the "forwardedportlocal" object, (so I don't make such an object, and I obviously don't start it) Then there is no memory issue. The client is created, and then disposed cleanly.
I can see this happening the diagnostic tool of visual studio.

I already added portfwld.stop() and portfwld.dispose() together with of course SshClient.disconnect() and SshClient.dispose()
but that did not help.

I made a version in vb.net and also one in c#, but the results are the same.

I also Commented the connection to the database to show that this is not the issue.

I hope someone can give me some insight of what is happening, or perhaps what I am doing wrong?
