[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 Tasks: 227 total, 2 running, 224 sleeping, 1 stopped, 0 zombie Cpu(s): 0.7%us, 1.0%sy, 0.0%ni, 0.0%id, 98.4%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 1551432k total, 1484768k used, 66664k free, 167556k buffers Swap: 2104476k total, 0k used, 2104476k free, 954052k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 5041 bruce 20 0 2504 1004 724 R 0.7 0.1 4:29.24 top 7379 bruce 20 0 2480 936 724 R 0.7 0.1 41:17.55 top 3500 bruce 20 0 594m 95m 46m S 0.3 6.3 1:45.16 amarok 1 root 20 0 2196 740 636 S 0.0 0.0 0:09.95 init 2 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kthreadd 3 root RT 0 0 0 0 S 0.0 0.0 0:00.00 migration/0 4 root 20 0 0 0 0 S 0.0 0.0 0:19.49 ksoftirqd/0 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?

No disk problems? Try iotop, tap o to see what process is doing IO to disk.
