Dropping windows clients after a bit...Ubuntu server

[Stuart Smith 0]

1.7.5 Synergy Pro: Kubuntu 15.04 acting as server, two Windows 7 Pro clients. Server sits in between both clients. Multiple screens attached to all PCs. All the monitors are switchable (using different inputs) to two computers with the center screen attached to all three. Workflow often involves setting all monitors to the Windows clients leaving the server un-viewed but still logically present. I am not using SSL and I am using port 22000 instead of the default. Every so often, both clients will drop connection to synergy. Since they both loose connectivity in the same event, I assume the problem is with the server. It seems to happen randomly or when using the clipboard on one of the clients - but not always. I also don't have consistent clipboard behavior - sometimes I can copy from one PC to another - sometimes not. Often, an attempt at pasting will cause the desktop on the server to freeze for a half a minute or so, then both clients will drop. Often, just clicking on the "Apply" button on the server synergy window will reconnect the clients, sometimes a Stop-Start is required. It also seems like it happens less often if I leave the Synergy window open on the server - which I've taken to since I have to reconnect the clients several times an hour or more. I would really like the ability to clip from one PC to another but it seems problematic.

Upped it to Debug1 and got this below. Client was not available, then all of a sudden was. This happened right after changing to Debug2 and attempt to scroll right. I only tried to slide the pointer - no actions taken on either desktop - server or client.
