Okay i have a strange problem. Im running a nextcloud instance with linuxserver.io docker. And every night at 03:00 AM i get 100% load. And it disapears when i restart the docker.
I have entered docker shell when the high loads occurs and i see that the process is php /app/www/public/cron.php that is causing the high load.
Nothing i the logs shows errors and i have checked all settings. How can i continue the search of what making the high load?
I cant trigger the high load from anything else execpt waiting until 03:00 AM.
Thanks!
I checked crontab -l
root@f6449ccdbac8:/#crontab -l do daily/weekly/monthly maintenance min hour day month weekday command */15 * * * * run-parts /etc/periodic/15min
0 * * * * run-parts /etc/periodic/hourly
0 2 * * * run-parts /etc/periodic/daily
0 3 * * 6 run-parts /etc/periodic/weekly
0 5 1 * * run-parts /etc/periodic/monthly
And under daily i found logrotate:
!/bin/sh
if [ -f /etc/conf.d/logrotate ]; then . /etc/conf.d/logrotate fi
if [ -x /usr/bin/cpulimit ] && [ -n “$CPULIMIT” ]; then _cpulimit=“/usr/bin/cpulimit --limit=$CPULIMIT” fi
$_cpulimit /usr/sbin/logrotate /etc/logrotate.conf -s /config/log/logrotate.status EXITVALUE=$? if [ $EXITVALUE != 0 ]; then /usr/bin/logger -t logrotate “ALERT exited abnormally with [$EXITVALUE]” fi exit 0
But i dont understand what could be wrong 🤔 maybe something with the logfile which is in a bind mount?
I will investigate further!
I don’t know enough about it, but it does seem like there are issues where logrotate can cause CPU overload issues like the one below.
