It is cronjobs for different tasks of watchdog module, for plesk-mobile extension, for renewal certificates of letsencrypt extension and task of panel-news extension.
Nothing suspicious.

Ok, thanks.

For example:

uptime -s
=> 2017-01-26 00:30:45

=========

This happens mostly in the night where no user is using the side. I try to watch the syslog, the memory and cpu usage but i cant find a reason for this. Have you got any idea?

Thanks for help!
