I have a root cron job that powers down my server every day at 1am and 6pm. The output of '# crontab -l' is shown below.
* 1,18 * * * poweroff
Last night, after the server powered down at 6pm, I decided I wanted to use the server so I started it with the power button. The server, after a minute or so, powered itself down. This behaviour happened repeatedly until I waited past 7pm. Then the server did not poweroff.
Apparently a cron job that executed correctly at 6pm was executing minutes past 6pm when the server was restarted. This is totally unexpected behavior.
Here is the output of the cron log file. The name of the server has been redacted.
# grep -i 'Feb 22' cron-20140223 | grep -i poweroff Feb 22 18:00:01 xxxxxxxxxx CROND[2875]: (root) CMD (poweroff) Feb 22 18:12:01 xxxxxxxxxx CROND[1894]: (root) CMD (poweroff) Feb 22 18:16:01 xxxxxxxxxx CROND[1893]: (root) CMD (poweroff) Feb 22 18:18:01 xxxxxxxxxx CROND[1896]: (root) CMD (poweroff) Feb 22 18:22:01 xxxxxxxxxx CROND[1915]: (root) CMD (poweroff) Feb 22 18:25:01 xxxxxxxxxx CROND[1919]: (root) CMD (poweroff) Feb 22 18:34:01 xxxxxxxxxx CROND[1890]: (root) CMD (poweroff)
Is there a fix for this behavior?
Thank you, Joe
