KSWAPD -

[Ian Derringer]

Hi,
Is there a way to restart or clean out Kswapd value? This is what my Kswapd look like at "top" overview:

6 root 15 0 0 0 0 SW 0.0 0.0 272:27 kswapd

On this particular server, we're running RHAS 2.1 kernel 2.4.9-e.3smp #1 SMP

Thanks,
Ian D.

I think the only way to reset the cpu-time counter of a process is... restart the process.
kswapd is the kernel process that manages the memory paging. The only thing you can do is reboot.

I don't think that you can clean out kswapd, but in the future I suggest you to update to the latest RHEL2.1 kernel - -57, as far as I remember.

being a kernel process you can not restart or stop the kswapd (which is used to manage the swapping and memory management).

if you are keen to avoid this only from the top output then check the man page for top to find out list of output format options. you can add or remove a column from the top output as you wish.

Hope this helps,
Gopi

I've heard that you can do echo 30 > /proc/sys/vm/inactive_clean_percent with Kernel .21 and obove. Unforntunately, with with my current version of 2.4.9-e.3smp #1

Does anyone know where I can go to download a newer Kernel to update my server?

Thanks,
Ian

if you are having subscription with RedHat then you should be able to download the latest update kernel from redhat website.

Go to RedHat website and check on the errata download page.

and if you don't have RHN sunscription, you still can download kernel sources from RH ftp.
The second way it's download kernel from CentOS or other RHEL clone.
