Hi Sungurus
Below is the output of top command ran on one of our servers, with
oracle database installed.
At the moment, the report shows that the percentage used by the kernel
is 44.8% which I believe its quite high.
And I am having 19gb swap space used.
Can anyone give me a technical clue to what might be the cause of this
result?

last pid: 23625; load averages: 22.35, 21.80, 20.30
12:10:22
143 processes: 122 sleeping, 14 running, 7 on cpu
CPU states: 0.1% idle, 55.0% user, 44.8% kernel, 0.0% iowait, 0.0%
swap
Memory: 16G real, 796M free, 19G swap in use, 7077M swap free
