Kcarb Posted May 22, 2017 Share Posted May 22, 2017 Hello, I have been using Synergy for a while now. I've always had one win10 PC (host) and one win7 PC (client) and it has worked with no problems. Recently the client was upgraded to win10 and since I have done that i have a had a lot of connectivity problems. When i move mouse to the client it disappears and freezes every few seconds then quickly reconnects and is fine. It does this every 20 to 30 seconds I would say. Any ideas?

Paul Suarez Posted May 22, 2017 Share Posted May 22, 2017 What Synergy versions do you have on each of your machines? Link to comment Share on other sites More sharing options...
Kcarb Posted May 22, 2017 Author Share Posted May 22, 2017 1.8.8 on both machines. Link to comment Share on other sites More sharing options...
Paul Suarez Posted May 22, 2017 Share Posted May 22, 2017 Can you try uninstalling it from your client machine first and re-install it after rebooting? Link to comment Share on other sites More sharing options...
Kcarb Posted May 24, 2017 Author Share Posted May 24, 2017 Re-installing on the client seems to have done the trick. Thank you! Link to comment Share on other sites More sharing options...

Kcarb Posted May 25, 2017 Author Share Posted May 25, 2017 Ok I may have jumped the gun! It seemed to solve the issue for a day or two but I am having the same problem today. As soonb as I move my mouse over to the client machine here it locks up and freezes pretty quickly, here is what the log shows each time (not sure if this helps): [2017-05-25T14:38:13] INFO: leaving screen [2017-05-25T14:38:22] NOTE: client "xxxxxxxxxx" is dead [2017-05-25T14:38:22] INFO: jump from "xxxxxxxxxx" to "host" Link to comment Share on other sites More sharing options...
Paul Suarez Posted May 25, 2017 Share Posted May 25, 2017 Do you have a third party firewall running on your client machine? Link to comment Share on other sites More sharing options...
Kcarb Posted June 6, 2017 Author Share Posted June 6, 2017 Hey Paul, i do have a firewall (it is a work computer so I can't remove it). That said I've had this same AV/Firewall back with windows 7. What i have noticed is that the problem seems to be happening only while I run Webex on the client machine. If I am not on webex everything is fine.

Kcarb Posted June 13, 2017 Author Share Posted June 13, 2017 That is correct. See the attached image, that is the same on both host and client. Link to comment Share on other sites More sharing options...

If I am not on webex everything is fine. Going back to this post. You said this only happens when Webex is running, right? If so, what WebEx meeting features are you usually using?

Kcarb Posted June 13, 2017 Author Share Posted June 13, 2017 Correct, that appears to be the only time it happens. Additionally it is only when i use Webex on the client (which is my work computer so I usually have to use it there). Typically Webex is just used for the conference line however the share screen functionality is also used at times and this is when it seems to be even worse.

Paul Suarez Posted June 13, 2017 Share Posted June 13, 2017 Well, I guess using it with WebEx share screen feature might be explainable. Are you normally presenting/sharing your screen?or you are the viewer of someone presents/shares? Is it happening on both scenarios? Link to comment Share on other sites More sharing options...
Kcarb Posted June 14, 2017 Author Share Posted June 14, 2017 It happens on both scenarios. I did some testing yesterday afternoon and it does seem to happen even when there is no sharing at all. So it appears to be the Webex application in general. Really odd Link to comment Share on other sites More sharing options...
Paul Suarez Posted June 14, 2017 Share Posted June 14, 2017 Hi @Kcarb . I had a think about this and it could be that a process(es) for Webex might be running/listening to the same port Synergy uses. You can try to check it with the method explained in How To Find Port Number by Process ID (PID) on Windows. Let us know how it goes. Link to comment Share on other sites More sharing options...
lutherm1 Posted June 23, 2017 Share Posted June 23, 2017 Just chiming in with a me too on this issue. Specifically when I have a webex session running on the synergy server (Cisco Webex meeting center on win10) and move the mouse off to either of my client screens (Redhat Linux and OS-X), the webex session will randomly freeze for 10s or so, and the Synergy client connections reset. The problem is intermittent, but ONLY occurs when the mouse is moved off of the synergy server host to one of the clients. Details on the ports used by webex are here: https://www.cisco.com/c/en/us/td/docs/collaboration/CWMS/2_0/Planning_Guide/Planning_Guide_chapter_011.html#reference_125F962B1D20407186B1654C7A3F5873 Link to comment Share on other sites More sharing options...
asan127 Posted June 26, 2017 Share Posted June 26, 2017 Chiming in as well. The repeated disconnects ONLY happen when the WebEx application is running. Worse when screen-sharing (either myself or someone else) is occurring. It happens on both the client and the sever, whichever is running WebEx. FYI: It's actually more than just Synergy locking up. I ran the Windows stopwatch app and noticed the timer stops completely for the duration of the freeze (typically 5-15 seconds), and then jumps forward to the appropriate time. It appears as though the entire computer is hung up for those moments, but then resumes as if nothing happened. I have been unable to find any reported errors in the Windows Event Logs, router logs, or Synergy debug logs (but I'm not 100% sure I know what I'm looking for in there).

Paul Suarez Posted June 27, 2017 Share Posted June 27, 2017 Have you checked Synergyd.exe too? This is for the Synergy service. Link to comment Share on other sites More sharing options...
lutherm1 Posted June 28, 2017 Share Posted June 28, 2017 I thought the daemon was just responsible for start/stop of the server pid, but nonetheless, here's the netstat info for synergyd.exe: C:\WINDOWS\system32>netstat -a -b -o | findstr 3540 TCP 127.0.0.1:24801 OLDBEAN:0 LISTENING 3540 TCP 127.0.0.1:24801 OLDBEAN:49686 ESTABLISHED 3540 Link to comment Share on other sites More sharing options...
lutherm1 Posted July 14, 2017 Share Posted July 14, 2017 Still seeing this problem when running the webex client and moving the mouse offscreen. Any further diagnostic information I can collect to help track this down? Link to comment Share on other sites More sharing options...
Paul Suarez Posted July 14, 2017 Share Posted July 14, 2017 Are you still running your machines with Synergy v1.8.8? If so,can you try uninstalling that and use v1.9.0rc3 instead? You can get it from the forums thread tagged below. Link to comment Share on other sites More sharing options...
