Jul 27 23:31:28 a1124016 syslog: STD-0382: cron process died on a1124016 more than 3 times in 24 hours

cron is still running on the box

a1124016:sk1798 ps -ef | grep -i cron

Hello Sahir,

This is very very strange.
what does crontab -l

is there any process or cron job that does this.

have you updated your sys with the latest patches. specially the cron patches.

can you kill yoursel the cron job and restart and see if this stops.

any other messages in /var/adm/syslog/syslog.log
and also in cron.log

Hi Sahir,

I think somewhere we need to redirect the logs. Let me find it and inform you...

Hi Sahir,

Verify next files:

/sbin/init.d/cron
/var/adm/cron/cron.allow

and users crontabs in:

/var/spool/cron/crontabs

man cron

There is nothing to do...

Actual problem was somebody renamed log files to OLDlog.. This was the reason, I renamed to log and problem resolved.

Hi,

Verify permission for log files

-rw-r--r-- 1 root root 0 Jun 6 03:44 OLDlog
-rw-r--r-- 1 root root 0 Jun 13 03:45 log

rgs,

cron (like syslogd and others) always keeps the log file open. Renaming the file does nothing but change the name. Once a file is open, you can even remove the file and the program will keep writing to the file. The file is simply marked for removal once all the links to the file are gone.

problem is solved by renaming log file. Thanks for all support
