Hey, It appears to be a problem with the lirc_imon driver and not with the LCDproc daemon. What I found out so far is this:
After loading the lirc_imon module you can write to /dev/lcd0 and text will appear on the display. You can also read from /dev/lirc0 and you'll see signals coming from the IR reciever or the Wheel in the frontpanel. When you would either read or write a lot of data from/to these devices the driver will somehow fail. The iMon device will be "disconnected" and immediately after that "reconnect" and be recognised by the lirc_imon driver again. The problem is that any programs that were reading/writing to these devices will no longer respond. For instance: LCDd needs to be restarted to be able to use the /dec/lcd0 device again and lirc needs to be restarted to be able to use /dev/lirc0. A simple way to trigger this problem (on my machine at least) is to execute the following command: cat /dev/lirc0 > /dev/lcd0 When you turn the Wheel around a lot (or press buttons on the remote) you'll see some characters appear on the LCD display and after a while (about a minute) it will stop responding. In the message log you'll see that the device got disconnected and reconnected again and messages about the iMon device not being available will also keep popping up until you kill the "cat" command. Maybe you can verify this and we should report this to Venky Raju (the iMon driver guy)?
