Subject [users@httpd] maybe DOS
Date Wed, 30 Nov 2005 08:41:49 GMT
Hi everybody,
I'm using Apache 2.0.55 with Prefork MPM on Linux 2.6.x. Yesterday I 
experienced really  bad things. Apache forked many proceses and consumed 
all of my memory (2GB) and swaps (2GB). The result was, that I had to 
restart the server (load > 60).

The bigest problem is, that I'm not able to recognize, what was the reason.

Is there any possible DOS with such result?

Is there any way, how to prevent Apache (or in general a proces) from 
consuming all of the memory. For example set Linux not to allow it to 
consume more than 1.5 GB of memory.

Many thanks.
