Php exec() return code is -1 when in a forked process, but 0 in a normal script
<p>I am using exec() inside a a script that runs as a daemon and forks child processes using the pear class Net_Server. </p>

<p>I am getting a strange issue whereby the return code (the third param of of exec) comes back as -1. When I run the command on the command line, or with exec in a normal php script the return code is 0 as it should be. Anyone have any idea why this is happening, and how to fix it? </p>
