Required info on Pstack on solaris10
Hi All ,
I am wanted to know the #of thread ( Kernal & User ) created by the Process
i was looking into the prstat
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
994 httpd 126M 99M sleep 58 0 1:11.25 2.4% ns-httpd/33
997 httpd 114M 86M sleep 58 0 0:40.02 2.7% ns-httpd/22
995 httpd 96M 68M sleep 59 0 0:18.01 1.0% ns-httpd/15
From the above values 994 {pid} have assocaiated with the 33 threads NLWP value .
But when have look the pstack output as below
