Hi Eduardo,
Try running kernel-hugemem instead of the normal kernel, I recently
had similar problems to you which were fixed by running
kernel-hugemem.
I upgraded the RAM in a machine from 2gb to 4gb and it ran really
slowly with the normal kernel, but fine with kernel-hugemem
yum install kernel-hugemem
rebboot and pick kernel-hugmem on boot.
Good luck,
Rhys

Hello to all.
First sorry my terrible english.
Some time ago we buy a new server on which we have installed SL-45.
The server has the following characteristics:
Super Micro motherboard
2 cpus dualcore Intel Xeon 2GHz
4GB of ram, 250GB of disc.
On that occasion the server had a LSI SATA RAID controller, with the raid with
two disks of 250GB. For some reason that we do not know that until today, the
disc access was very slow, at the point of the machine go getting increasingly
slow until freeze. This happened in a short time, a matter of minutes after
start the nfs server. The only thing I could find is that, looking at the top,
we getting all processors increased the wa nearly 100% with us less than 10%
in all processors. We remove the raid controller and made the raid via
software and the problem had apparently disappeared. Today, doing some
searches through files, commands such as du and find took too long, turning
the wa to stay near 80% in almost all processors, with the difference that
when I concluded the program, the system returned to normal.
Please send me any suggestion that I continue to research.
Thank you now.
Eduardo Bach
