My server has been crashing quite alot lately, it does have some high traffic sites on there but it has never really been this bad before. Today i noticed these in cpanel, what are they and is there anyway I can control them? :/ Screenshot: any help appreciated.
netstat is a utility that displays various network statistics. I would suspect that your hosting provider is running this on a regular basis to monitor the network. The sadc process is SAR (System Activity Reporter). It gathers system performance statistics. They are probably being run as root, and your probably don't have any control over them (unless you are on a dedicated server).
Typically, sar is scheduled through cron, so check your crontab entries. It's hard to tell for sure without seeing the process tree.
