 |
|
I just discovered that cron has died on one of the machines and it wont restart.
| Code: |
x init.d # /etc/init.d/vcron restart
* Starting vcron... [ !! ]
x init.d # start-stop-daemon --start --exec /usr/sbin/cron
/usr/sbin/cron already running
x init.d # cat /var/run/cron.pid
cat: /var/run/cron.pid: No such file or directory
|
The last change to crontab was made nearly a month ago.
Any hints? |

Have you done:
| Code: | | ps -elf | grep vcron |
to see if there's really a vcron running?
If there is do a
and then
| Code: | | /etc/init.d/vcron start |
You might also need to do
| Code: | | /etc/init.d/vcron zap |
before the start if the vcron left other stale files around. |

Thank you a quick reply. I had already made sure that vcron was not running. But when using your arguments to ps I get a strange error.
| Code: |
x init.d # ps -elf | grep vcron
Warning: /usr/src/linux/System.map has an incorrect kernel version.

Hmm... strange. I've seen that warning before. I think I had /boot mounted and had an incorrect System.map file there. Somehow the kernel was looking at that. Since I don't know what the System.map is for and never usually need it, I just deleted that one from /boot but I don't recommend you do the same since it could bork your system.
When you run the zap command does it allow your vcron to start? |

Have you looked for clues in your logs? See if there are any references to vcron... there should at least be a line from the /etc/init.d/vcron script. Look for errors after that.
Also, if that doesn't show you what's wrong, try running cron from the command line to see if it tells you what's going on. |

A manual restart seems to be working though this is far from a perfect solution.
| Code: |
x log # /etc/init.d/vcron status
* status: stopped
x log # ps aux | grep cron
root 25369 0.0 0.0 1452 648 ? S 2004 0:00 /usr/sbin/cron
root 25492 0.0 0.0 1400 496 pts/0 R 2004 0:00 grep cron
|
Now I just hope it will keep running 
Thank you for the help if you get any ideas about what is wrong I would really like to fix this in a nicer way. |

| Did you look in your logs for any clues? Anything if you run dmesg? |

No clues in any of the log files. CRON just quietly dies 
The system has been up for nearly a month I cannot see what I should use dmesg for? |
