Dear all expert here,

Here is my message after I process - cat /proc/meminfo

Code:

[root@dg01 ~]# cat /proc/meminfo

Could anyone tell me please why my SwapFree is empty and how can I check which one are using it (I mean OS or Application)?

Would be appreciate for your help.

Regards,
Pitou

This will tell you which processes have a large virtual memory size, which is not exactly the same thing.

Code:

ps waux |awk '{if ($5 > 1000000) print $0}'

This may be simpler / easier to read as it only shows you the process Id, percentage and command lines of processes using thirty percent memory (RSS) or more:

Code:

\ps --no-headers -eopid,%mem,cmd ax --sort=%mem|awk '{if ($2 > 30) print}'
