I have AIX 6.1 machine that is occasionally became very slow.
There is DB2 installed on this machine, but running topas show no obvious reason for this slowness.
CPU: is above 95% idle on both CPU’s.
Network: usually less than 10kbps load.
Disks: less than 5% busy most of the time.
Memory: from 16GB 27.7% comp, 8.8% noncomp and 8.8% client
Paging: size 4GB 100% free
Any idea how do I find what’s causing the system to be almost unresponsive? only after reboot we can work with the system until the next time…
