Howdy. I'm getting a weird problem with Apache on a RHEL2.1 box I have. It does on the _second_ HUP or USR1 signal it receives. So ever two days logrotate kills it. It seems to be dying when PHP reloads for the second time. Anyone have any useful ideas on how to track this problem down more precisely?
