Title: Crond extreme CPU usage
Post by: TioRuben on March 04, 2013, 10:53:48 PM
Hi all!
I've an Olinuxino Mini Wifi Board. I've just installed the latest ArchLinux ARM image from Archlinux's website. I have some issues about CPU load affecting to overall performance. After a ps -aux command, I can see this:
Code: [Select]
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
...
root      1179 47.6  2.3   4804  1252 ?        Rs   20:39   2:56 /usr/sbin/crond -n
...
The cron daemon loads about 40~50% of the CPU (and there is not any cron job in crontab). This makes the system very slow, even using terminal is exasperating... Anyone have the same problem? I understand that maybe a proccess started by cron could load the CPU, but not the crond itself.

Thanks in advance

Yes i have that problem too. Cron is using 99% processor time. After a few minutes it stops though!

Hi, I have the same problem. crond is using 40% - 45% cpu and bogging down the system..

Did anyone find a fix to this ? running stock 2.6 kernel.
