The code in your script:
implies that you believe that writing the string Now exiting. to standard output from your script causes the script to stop running. It does not do that. It simply writes that text and continues running the rest of the code in your script. In this case, it sleeps for two seconds and breaks out of the loop looking for files being downloaded. And, then it immediately starts testing for the conditions you have set up to be verified as being present before you suspend your computer. If you want your script to exit (as indicated by your echo statement), you need to actually include an exit statement in your code!
Does anyone know if there is a UNIX-tool available that constantly will check if (some specific) deamons are running and will notify (via email) if one has failed/stopped?

ignore_user_abort
IGNORE_USER_ABORT(3) 1 IGNORE_USER_ABORT(3)ignore_user_abort - Set whether a client disconnect should abort script executionSYNOPSIS
int ignore_user_abort ([string $value])
DESCRIPTION
Sets whether a client disconnect should cause a script to be aborted.
When running PHP as a command line script, and the script's tty goes away without the script being terminated then the script will die the
next time it tries to write anything, unless $value is set to TRUE
PARAMETERS
o $value
- If set, this function will set the ignore_user_abort ini setting to the given $value. If not, this function will only return the
previous setting without changing it.
RETURN VALUES
Returns the previous setting, as an integer.
EXAMPLES
Example #1
A ignore_user_abort(3) example
<?php
// Ignore user aborts and allow the script
// to run forever
ignore_user_abort(true);
set_time_limit(0);
echo 'Testing connection handling in PHP';
// Run a pointless loop that sometime
// hopefully will make us click away from
// page or click the "Stop" button.
while(1)
{
// Did the connection fail?
if(connection_status() != CONNECTION_NORMAL)
{
break;
}
// Sleep for 10 seconds
sleep(10);
}
// If this is reached, then the 'break'
// was triggered from inside the while loop
// So here we can log, or perform any other tasks
// we need without actually being dependent on the
// browser.
?>
NOTES
PHP will not detect that the user has aborted the connection until an attempt is made to send information to the client. Simply using an
echo statement does not guarantee that information is sent, see flush(3).
SEE ALSO connection_aborted(3), connection_status(3), Connection Handling for a complete description of connection handling in PHP. .
