Port Forwarding Causing RDM and PC to hang.
When running a SSH port-forwarding session every time the channels are opened and closed RDM becomes unresponsive.
When analyzing the process it says it's waiting on network I/O.
"One or more threads of RemoteDesktopMangerFree.exe are waiting waiting to finish network I/O"
This is causing the PC to lag to the extent that typing is very delayed.
Kind regards,

Hello,
Engineering has asked me to ask you a couple of questions to clarify certain details regarding your issue.
- When you experience the issue, does your whole computer hang or only RDM?
- What do you use your SSH tunnels with? Are they for terminals, RDP sessions or something else?
- Do you have logging enabled for your port-forward session? If you do, is the path local or remote?
Best regards,

Hi Gabriel,
- When you experience the issue, does your whole computer hang or only RDM?
RDM becomes unresponsive up for 30-45 secs every 30 seconds and my computer becomes very slow, I see the process spike heavily. These symptoms seem to worsen the longer I have the port-forwarding running.
- What do you use your SSH tunnels with? Are they for terminals, RDP sessions or something else?
Web-browsing sessions to manage the GUI of firewalls.
- Do you have logging enabled for your port-forward session? If you do, is the path local or remote?
Logging is not enabled.

Hello,
We've identified what might be causing these freezes and slowdowns. We modified how the SSH Tunnel and Portforward entries show their logs, as we believe this was causing the issue. The change will be available in RDM 2020.3.15.0, which we hope to release soon.
