popen - premature process death

Well, this worked somewhat well for a time. Now when I run this, I see about half a second's worth of output from the command, and then the page hangs. Looking at "ps" on the server, I see that there's a DEFUNCT sh process owned by apache (PHP is not running as CGI) that's been zombified. It looks as if the command is getting killed within half a second of being run. Like I said, this just started screwing up all of the sudden -- Unfortunately, I can't remember whether or not I changed any important configuration variables that might have affected this. I'm pretty sure that I haven't.
Any clues? I even get the same problem with passthru().

I'm writing a script that needs to call some perl scripts in the same directory as the running PHP script. It looks something like this:Code: Select all
echo "<p id=\"output\">";
$handle = popen( "perl command.pl $args", "r" );
while( !feof($handle) )
{
echo nl2br(fgets($handle));
}
pclose($handle);
echo "</p>";Any clues? I even get the same problem with passthru().
