I use a lot of ePN checks. It does COW in a lot of situations, but most of the time you follow up with an exec, so almost no writes occur before a new process overwrites it anyway. Also, there's no way that a normal fork is going to be contributing more than an insignificant amount to a 350 second delay. At 45% system CPU, something else is occuring. Is the machine out of memory and swapping? Is one of the scripts fork bombing or respawing a single child that exits rapidly? (I might use 'top' and watch how fast the 'last PID' is increasing.) -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
