[ale] odd log message

[Sean]

my main log file is filling up with this message:

>May 19 22:31:42 localhost init: Id "co" respawning too fast: disabled for 
5 minutes
>May 19 22:38:23 localhost init: Id "co" respawning too fast: disabled for 
5 minutes
>May 19 22:45:04 localhost init: Id "co" respawning too fast: disabled for 
5 minutes

I would appreciate a clue as to what might be going on.
This is a FC7 system.
