In my case I also experience the problem after the machine has been asleep for some unknown length of time greater than a few minutes. But my FE acts as though it has dropped the UDP port connected to lircd on my BE, so it is unable to receive remote control keypresses. IIRC, things work perfectly from the keyboard.

Here's my setup:

1. I use RF remote controls, which send a signal to a single receiver in 
the basement.
2. The receiver converts the RF signal to IR and blasts it into my 
HDHomeRun.
3. The HDHR talks to LIRC, running the UDP driver, on the backend machine.
4. The frontend machines all talk to the backend LIRC instance.

It's something to do with the TCP connection between the frontend and 
the backend getting dropped if the frontend machine is in S3 idle for 
too long. (Note that I said UDP in my original post; I just verified 
that it is TCP.)
