Hello !
I have simple php script
<?php
$number = 3000;
while($number > 0) {
$number--;
sleep(2);
}
?>
In apache I have 30 second timeout set so the apache tries to kill the process
but got EPERM from kill()

waitpid(3131, 0xbff03224, WSTOPPED) = ? ERESTARTSYS (To be restarted)
So there is some wrong with mod_suphp ,apache is unable to kill the php process
if the timeout is reached.
regards,
Piotr
