Dear all, there are times after my opensuse 12.1 is running for some period, like 5-6 days without rebooting, that the performance goes really down. It reminds me the old days of windows 98 where one had to reboot system quite a lot to keep performance up.
When this happes everything goes too slow (I have a four core cpu). Ksnapshot make 3-4 seconds to appear, writing text makes 2-3 seconds to appear in screen and so on....
What I tried intuitively is to understand if there is something eating up my cpu.
In the image below
Imageshack - cpulost.jpg you will notice the problem
On the middle bottom ksysguard reports cput at 75%, which can be an indicator why the system is slowing down. Also the graphs show the four cpus being quite busy.
On the left side there is a ksysguard again showing the active processes ordered by cpu utilization, where you can see that the total sum of percentages does not get even close to the 75% .
Then I thought that there might be some root processes (I am the only one using that machine) eating the cpu so I sudo top. On the right side you will find the top running with root permissions.
Even there the cpu utilization reported does not get close to the 75%
What I am missing here and why I can not find what is eating cpu and makes system unresponive?
Could you please help me with that?
Regards
Alex
