I think it is a Code Red or Nimda worm, not sure which one but it is a IIS-Webserver Exploit

Nef,

As Jochen has already mentioned the first part of the log

[Fri Apr 4 09:50:31 2003] [error] [client 210.125.151.233] File does not exist: /home/e-smith/files/primary/html/default.ida

is code-red worm. It is totally harmless to linux servers.

The second part where you are reaching MaxClient settings and having Apache close down is, I suspect, due to a looping reference in your "error 400 message page". Every time you get a code red hit it will create an error 400 message which is looping creating another http process, which is looping creating another http process, and so on until you reach the MaxClient limits.

Have you modified or added your own error pages by any chance

Jon
