Me too, so when I had this sudden swap problem for the first time, I |
| 10 |
searched for a method to do this and found a script here: |
| 11 |
http://northernmost.org/blog/find-out-what-is-using-your-swap/ |
| 12 |
|
| 13 |
There's lots of information for all processes in /proc/<pid>/. Trying to |
| 14 |
read /proc/<pid>/mem (I think it was this file) in mc was not such a good |
| 15 |
idea, the system froze with lots of HD activity, and after half an hour I |
| 16 |
rebooted with Alt-SysRq-{K,E,I,S,U,B}. |
| 17 |
|
| 18 |
I improved the script a little, it allows sorting by PID, size and name, |
| 19 |
and can restrict the output to specific processes or show only those |
| 20 |
using more swap than specified. If interested you can download it here: |

| 22 |
You need to be root to see processes you do not own. |
| 23 |
|
| 24 |
But of course, I forgot to run it after the sudden swap problem happened |
| 25 |
lately. So I still do not know what was going on there. I'll wait for the |
| 26 |
next time it happens. |
