Hello,

load average on my system is very high.
And everything looks fine. But don't know the reason behind high load average.

Any help would be appreciated...!!!!

I'd say you load average is skewed due to the number of tasks:
Most systems I see have <500 ... are all 3330 tasks actually required?

Hey thanks...!!!

But i found the problem..
It was due to a NFS Filesystem which was mounted on the system.
But nfs service was stopped on the source server.
