[opensuse] openSUSE 11.3 > top reports CPU 98.4%wa,
Hi,

Assuming here that 98.4%wa represents 98.4% of the time the CPU is waiting.
Is there a way to determine what the CPU is waiting for when top reports the
following?

top - 09:56:53 up 7 days, 18:57, 26 users, load average: 37.52, 29.82, 29.43

This occurs when I turn on SAMBA server on this machine and try to access the
SAMBA share from another machine. The machine is running openSUSE 11.3 on this
desktop server and on a laptop. The desktop is configured as the PDC. The
laptop is set as Not a Domain Controller. There are Windows XP machines on the
domain also.
The first time that a windows XP machine tries to access a share it was
successful, but then if the winXP Explorer window is closed then re-opened it
does not login anymore and the SAMBA server goes into waiting mode.

The server got into this waiting mode last night and has been like this for
9hrs now. I will need to reboot the machine to get it out of this more or
stop SAMBA with
/etc/init.d/smb stop

or just restart with
/etc/init.d/smb restart


This problem has occured since I installed openSUSE last January. Occasionally
there was suitable functionality. I have been partly suspicious that this
might be a networking problem since a some point I tried to get DNS running
which is not working on the same server. Could a broken DNS cause problems
with SAMBA?

Thanks Bruce.
