How to restart cron on Sun OS 5.10
How to restart cron on Sun OS 5.10 without restarting the server? The system administrator used
/etc/cron restart
and killed the FIFO file. I believe now it is running two cron daemons as the log show each scheduled script being run twice. ps -f grep cron shows
  root  6147   1  0  Dec 29 ?      0:01 /usr/sbin/cron
  root  7377   1  0  Dec 29 ?      0:01 /etc/cron restart
The log file example
>Â CMD: /somedir/subdir/script1>/d
> root 24236 c Tue Jan  5 04:00:00 2010
>Â CMD: /somedir/subdir/script2>/d
> root 24237 c Tue Jan  5 04:00:00 2010
>Â CMD: /somedir/subdir/script3>/d
> root 24240 c Tue Jan  5 04:00:00 2010
>Â CMD: /somedir/subdir/script1>/d
> root 24258 c Tue Jan  5 04:00:00 2010
>Â CMD: /somedir/subdir/script2>/d
> root 24259 c Tue Jan  5 04:00:00 2010
>Â CMD: /somedir/subdir/script3>/d
> root 24266 c Tue Jan  5 04:00:01 2010
The uname -a returns
SunOS ServerName 5.10 Generic sun4u sparc SUNW,Sun-Fire-V240
ls -l /etc/init.d/cron returns
/etc/init.d/cron: No such file or directory

What is /system/cron? There is no cron in /system.
Nevermind, should have read svsc man before posting :)
Yup, the 'svc:/system/cron:default'

svcadm restart -t system/cron:default
Worked like a charm. For the duplicate cron, the processes were killed using kill. Thanks everyone.

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
