The follo wing info is in my config: How many processes are running at the time, both total and for the user Apache runs as? What does cat /proc/sys/kernel/file-max show? Do you have any reason to think this is anything other than Linux simply running into file or process number restrictions? Linux has some very annoying such restrictions that can be a pain to remove. What ulimit returns means nothing if the kernel limits are lower.

So ps ax | wc will show those numbers? Are you sure that the ulimits you show are the ones set when Apache is started? What does cat /proc/sys/kernel/file-max show? 1024 Do you have any reason to think this is anything other than Linux simply running into file or process number restrictions? Linux has some very annoying such restrictions that can be a pain to remove. Yeah I have removed as many file limits as I could find. Unfortunatly the 3 other machines are running the exact same config without the problem popping up. Either it is a hard ware problem with the PII 400's or it is something I cannot figure. This is most likely a Linux problem. The other servers may well have slightly different traffic distribution, different numbers of CGIs, etc.

Comment-Added-By: lars Comment-Added-When: Fri Nov 6 10:26:46 PST 1998 Comment-Added: Are you using NFS? Any third party modules? No. NFS is disabled, and we did not compile any 3rd party modules into the server. The only extra module that I enabled was the status module. The server ran fine for about 6 months before this started. Is there anything in the OS itself that may have changed to cause this problem? Did you upgrade your kernel version or any libraries, especially libc around when it started happening? No, we did not make any such changes to the machine since the end of Septemper. This problem started well afterwards. It is a friend's machine, and he did tell me one thing that is interesting about this problem: it seems to be happening consistently between 6:30am and 8:30am CST. We checked for cron jobs running at this time, and we didn't find any. Are there any new attacks against the server that you know of that could cause this behavior?
