[Asterisk-Users] AGI and broken pipe

Hi All,

I was able to track down what I believe is a bug when using AGI
services. This bug may crash your system if your extensions.conf script
is intensive in using AGI services. Depending on your system's ulimit, *
keeps opening files until it reaches the system limit and then stops

Function app_agi/launch_script seems to leave an open and unused file.
Can someone confirm this? Below is a patch that solves the problem.
