Checks: Look for important VSZ, %CPU and %MEM results. Match application names and PIDs.

Checks: Look for dependencies, each process is started by a father. The init process has PID number 1 so it
will father many processes. In the sample output above, PID 605 has been started by PID 28260. Processes
IDs are re-used so a higher number is not always a more recent process.
In order to list the processes sorted by their memory virtual size, use the following command:
ps –auxww | sort –k 5 –rn > list_of_processes
The file list_of_processes will contain the list of processes and their virtual memory size. The first process in
the list will be the one with the biggest virtual memory size.
