high cpu utilization


I am hitting high cpu util.

Following observations:
console hung.
Pings success, but tcp based applications not going through. SSH,scp etc.
Few tasks started as RT, some of them don't show up in top.
Tried putting top in batch mode running every second, with RT priority.
top -b -n 1000000 -d 3

Its indicating the idle time as 0% but not pinpointing to any of tasks.
As per my understanding TOP display main thread stats only. I have applications with more than one tasks and few of them real time too

U can view the currently active process, just by giving top i command line.

even if the idle goes 0% no issues, main thing is the load average.

whats the load average.
