Main Node Load!




Posted by persianwhois, 05-18-2009, 09:24 AM
My main node load average is: load average: 485.91, 482.41, 481.80 And its very high! I checked all vps load is below than 3 So, why main node load is very high? Help me to find where is issue. Thank You

If you run 'top' do you see any applications taking up significant CPU or Memory ? Does 'vmstat' show a large amount of swapping on the main node ? What all is running ?

Run vzlist -o vpsid,laverage See if any of the VPS are reporting high load

check top-c. Load is not taken by VPSes.... May be some attack to main node

yes.. It looks like attack to the main node rather than any certain VPS attack... Check the main node
