Why netstat -p doesn't show PID of established connections?

  • 772

I have some REST service which is listening on tcp/8051
I'm querying this service with curl in infinite loop from the same host:
while true; do curl --header "Authorization: Bearer NDkwMjM3NzEtN2U2NS00ZDVkLThhYzItOThmZTliODljNWJj" -k "https://x.x.7.131:8051/status/service"; done

In other window i'm checking connections with netstat (under root):
while true; do netstat -antep |grep :8051 && echo ""; done

Output of netstat
