Hello, I have run into a strange problem. I have a simple Perl script which looks at the process table entries using the command: 
my @lines = `ps x`;

[download]
When run from the command-line, all works fine. But when I access the script using the webbrowser and Apache, the perl script is started but hangs on the backticks statement. The file permissions of the Perl script are ok, and also Apache is using the correct user and group while executing the Perl script.

I also tried using a pipe instead of backticks, but the script also hangs on the pipe open.

What might be the cause of this hang?

Best regards
