I'm not sure what was going wrong here, but, in any case, I'd strongly 
reccomend that anybody using Hawkeye use the new configuration syntax.

It's possible that you've encounterred this bug:  If you have jobs specified 
with the "old syntax" and the "new syntax", all jobs in the old syntax are 
silently ignored.  This bug will be corrected in 6.7.17 when it's released 
(but it'll log a warning in the log file about the use of the old syntax).

I'll have to look at what the manual says, but the correct syntax should be 
something like this:

STARTD_CRON_NAME = HAWKEYE
HAWKEYE_JOBLIST = NWS
HAWKEYE_NWS_EXECUTABLE = "/bin/cat"
HAWKEYE_NWS_ARGS = "/home/graziano/test"
HAWKEYE_NWS_MODE = "period"
HAWKEYE_NWS_PERIOD = "10s"

Notice the "HAWKEYE_" at the start of all of the NWS_ definitions.

Let me know if this doesn't help.

Also, to anybody else who might be reading this, don't use Hawkeye for 6.7.15 
-- which got pulled because the Hawkeye (cron) mechanism was completely 
broken.
