I will give it a try. touch /var/account/acct accton how long does it take for anything to get written to that file? As far as fork storms, I did noticed 1. I had the junior admin write a script to restart apache if LA got to high ....doing a truss on the pid i did noticed mad processes and his perl script hitting 10% cpu at times. Looking at it it was just a basic infinite while loop checking `uptime`. I have taken that script off but I don;t think that is what is causing this swap issue. Checking the hardware as well I have confirmed that the manufacter for these machines only included a heat sink and this tiny fan not big enough for these boxes....so cooling of the chip may be an issue as well.....gonna have to check over a bunch of things next couple days.
