Hi

We have a couple of machines running that kernel, serving some SAP systems
and some standalone Oracle databases and encountered any problems at all.
The problem you are describing, refers to a hardware problem, mostly.

What does /var/log/messages and /var/log/warn say. If the machine hangs
while you are entering commands which have to be loaded from disk (like top
and some others) I think there is a problem with you disk or disk
controller.

Does the disk light flashing while you are executing some commands (I know,
it is async I/O normally, but if there is no load, the machine will grep it
from disk immediately)? Is there any swap or is swap space just to small?

Hi,

we just installed a Central Instance (4.6 C - Kernel 4.6D 1293) on Linux
(SUSE SLES) running Kernel 2.4.18-64GB-SMP.
The database resides on a HP-UX machine.
It seems we have a problem with this Linux system. (Not the SAP part ....)
If you do ls -l or top or whatever you want - sometime the system hangs for
some minutes without
doing anything...

Are there any known problems with this kernel ?
What can we do to analyze this behavior ?

thanks

Armin
