The Tcl discussed in this forum is Tcl IVR API, a sepecific API for voice call. Looks like you are doing IOS Tcl.
My suggection is to post it in Cisco Beyond - https://supportforums.cisco.com/community/netpro/network-infrastructure/eem
And I would just ask the what is reqiured maybe they have other way to fulfill your requirement.
Thanks !

Hi
We are spawning scp command from the tcl script.
scp_client is going to defunct state which means scp_client process has finished everything and exited but still waiting for its parent process (in this case it is the tcl which has started scp_client process) to give signal.
Due to this even though the scp copy is success tcl script is not terminated/exited once copy is finished.
The same tcl exits fine if it is executed via CLI(Interactive mode) and [color=black]all processes are terminated properly.[/color]
Attached the tcl file we are using.
Please let us know if anyone has solution.
Here is definition of defunct/zombie process.
Zombie process, also known as defunct process, is a process which is no longer in effect. A defunct process exists, when the process killed or exited using exit system call, but has yet to receive a wait call from its parent process.
Defunct process occurs, if the parent process ignores the SIGCHLD. That's why the zombie process entry will be left in the process table
