[tictimed] Catastrophic file error - zero length

LWACT is removing the zero byte file and starting afresh. Occurs when the availability datagram file turns to 0 bytes in size for an unknown reason.

Action: For pre-LWACT 3.2 installation, remove the zero byte file, tictimed will recreate it. For LWACT 3.2 or higher versions, no action is required. LWACT will automatically remove the zero byte file.
