Hello, |
| 2 |
|
| 3 |
I can confirm it - I rarely open them, because my mailprogram will run |
| 4 |
out of resources. |
| 5 |
One difference though, I get them once every 24 hour (around midnight). |
| 6 |
|
| 7 |
So I just figured that it was because I had done something bad with my |
| 8 |
system :-) |
| 9 |
|
| 10 |
My crontab as it is now: |
| 11 |
--- begin |
| 12 |
# Global variables |
| 13 |
SHELL=/bin/bash |
| 14 |
PATH=/sbin:/bin:/usr/sbin:/usr/bin |
| 15 |
MAILTO=root |
| 16 |
HOME=/ |
| 17 |
|
| 18 |
# check scripts in cron.hourly, cron.daily, cron.weekly and cron.monthly |
| 19 |
0 * * * * rm -f /var/spool/cron/lastrun/cron.hourly |
| 20 |
1 3 * * * rm -f /var/spool/cron/lastrun/cron.daily |
| 21 |
15 4 * * 6 rm -f /var/spool/cron/lastrun/cron.weekly |
| 22 |
30 5 1 * * rm -f /var/spool/cron/lastrun/cron.monthly |
| 23 |
*/10 * * * * test -x /usr/sbin/run-crons && /usr/sbin/run-crons |
| 24 |
0 0 * * * /usr/sbin/logwatch.pl >/dev/null 2>&1 |
| 25 |
0 0 * * * /etc/init.d/ntp-client restart >/dev/null 2>&1 |
| 26 |
--- end |
| 27 |
|
| 28 |
And I know those two last lines look might weird, I've been too lazy to |
| 29 |
change them.. They work. |
