This is too much load, how to fix ? 1 Min Load Avg: 163.75 5 Min Load Avg: 168.46 15 Min Load Avg: 171.25 Running/Total Processes: 4/744 Secondly, I also get these emails: While processing the log files for user cyberinf, the cpu has been maxed out for more than a 6 hour period.

  Hi Rahail, Load issue can be trace with the below mentioned commands. #top -c check which process or user is generating the load issue in the server. #pstree -apu From the process list check any suspicious process running in the server. #netstat -plan|grep :80|awk {'print $5'}|cut -d: -f 1|sort|uniq -c|sort -nk 1 Check DOS or DDOS attack to the server. #netstat -ntuplaee Verify all the ports are known ports. If you found any unknown port trace the process id and trace it with lsof command. If the issue persist, feel free to update. I am happy to assist you in this.
