Hello All;
Lot of people suggested me to look into cron, but cron is not running
anything for every 5 min. I think It's the patch level where I need to
look, uname cmd shows this.
======================================
# uname -a
SunOS cds11744 5.7 Generic_106541-17 sun4u sparc SUNW,Ultra-Enterprise

Thanks & Regards;

Subject: CPU utilization gives spikes in every 5 min.
Hello Gurus;
I have a sun machine having 12 processors, 53GB of RAM.
It's giving spikes in CPU utilization in every 4-5 min. I also observed
that , this behaviour increases in 15-20 days after rebooting and goes
upto 90-95 % utilization spikes. It's mainly "sys" , i.e kernel which is
consuming the CPU cycles. Is it related to OS misbehaving?
Help is appreciated and I will summarize.
Here is the sar o/p
