One of outsourcing customer is suffering from
high cpu usage and defunct process when using tprof.
Customer is using tprof many times to monitor the system.
Cpu usage is very important for outsourcing customer
because of billing issue.
So, customer drives us strongly.
tprof became defunct process(%CPU used 56.5)
.
Q> Why is defunct cpu usage(56.5%) so high?
Could you explain it to us to understand customer?
.
Thank you in advance.
Regards.
