Hello; I have not had experience with this in the past but I am doing a large project in php and I need to know what Apache sends the browser when it is having memory problems. For test purposes when I have users test the program I want to be able to get a feel for how much memory I can expect it to use, when it gets used and what the user will see. Presently the machine this program is on is a machine that will be running Apache with ssl and php v5.2.1, gd, and mcrypt and has 1Gb of DDR2 memory installed. Has the doc root on a 15k SCSI drive that is dedicated to the file system that contains the document root tree. It is not /usr, where all the software is. That is on another 15k SCSI drive. So I would not think access times to be too much of an issue. But the php scripts will do a lot of file reading and writing (not e-mail). httpd is the only server that will be running on this machine as it is a production server and will be running headless, thus no GUI. It will be running ftpd but only for posting content and scripts that have already been proven on a development server on inside network, (ftp, telnet, ssh are blocked on public network and no mail server will be running) Thanks in advance Jeff K --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
