Every engineer needs to make a living, so is every software engineer. And license is an important piece of that big pie. Often times, FLEXlm is used to manage the license.
Occasionally, the license hangs due to crash on the client side. And here is how to kill a zombie license:
Use lmutil stat -a
to find out that hanging license, which includes:
port_number on the license server
And use the following to remove the hanging license:
lmutil lmremove -c port_num@server_name license_name user_name user_computer display
*) Sometimes "display" is the same as user_computer, sometimes it is just a number. (probably with an underscore in the middle)
