I installed keyclone, set up my macros, and got everything running today. But after a while i noticed that randomly, keyclone would stop sending "2" to my second slave client.

Example

When i first run keyclone:

Main shaman presses "2" for lightning bolt
Client 2 presses "2"
client 3 presses "2"

After a few minutes:
Main shaman presses "2" for lightning bolt
client 3 presses "2"
Client 2 stands there like an idiot...

The only way to fix it is to restart keyclone, which is impossible because even after you close keyclone, you still get the "another copy is already running" if you try to run it again.
