[facebo53]

Hello,
I set up my cron jobs in the following timings.. They donot conflict with others and even does not run after 5 minutes when last cron is finished...
0 22 * * * /usr/bin/curl --silent http://cron1
30 22 * * * /usr/bin/curl --silent http://cron2
0 23,0,1,2,3,4,5,6,7,8,9,10,11,12,13 * * * /usr/bin/curl --silent http://cron3
30 23,2,5,8,11,14 * * * /usr/bin/curl --silent http://cron4
0 0 * * 0 /usr/bin/curl --silent http://cron5

Thanks
