SSHClient: ForwardedPortLocal: memory issue

ConnectSSH エントリポイントと、レポートに示されている ForwardedPortLocal の繰り返し作成から始めます。一晩中実行するシナリオまたは繰り返し呼び出すシナリオを再現し、その後、ポートフォワーディングのライフサイクルと破棄の動作を追跡します。繰り返し接続してもメモリ使用量が継続的に増加しなくなれば完了です。

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?
