Fwd: socket: Too many open files

>I?m running a script which basically does a traceroute to the list of
hosts provided, and then pulls up some info by logging in to gateways in
the path.
>I am running this script for a list of almost 40k hosts in our data

after I reach some 5k to 6k hosts.

this is one reason for exhaustion of file descriptors.

I dont understand how I should close the socket created by commands module
after I do traceroute to one host.
Also, if I?m not wrong, isn?t commands module supposed to do that on its
