Does anyone know why apache is failing some times on cgi files?

For example apache is running but cgi files show up as a blank page. To fix it apache needs to be amually restarted. Ones the cgi files are running good, in 10 or 20 minutes they show up as a blank page again, even though apache is running.

Thanks

The problems has to do with the kernel not being compiled to handle that many open files at once. I am assuming you are running linux and have many sites on that machine. To fix this issue, you need to recompile the krenel to be able to handle more simultaneous open files.
