Aggregate Error in mac os HighSierra

[zymr-keshav]

Macos v 10.1.3.3 ( High Sierra)

There is a process running on the port 8083 ; I have checked from lsof command and When I try to kill a process using port number than it gives following error:

fkill :8083

$ fkill gpg
? Error killing process. Would you like to use the force? Yes
