from several minutes to  several hours. At first the web server seems to
stabilize i mean after some dozen of minutes and a strong load the memory
free keeps to 10 MB left and average load around 0.05 to 0.1. Then suddenly
some of the http process starts to consume high cpu load and the systems
starts to swap. At that time of course all is very slow and almost
impossible to use shell commands. This ends in 2 possiblities, either the
kernel manages to kill the httpd process after some long mins or i have to
reboot the systems.

and shntl files. Only special directives used are expires ones. All the
files are served from an nfs mount (wich is probably one of the bigest part
of the cached memory). We use as well a dozen of virutal host, each with lot
of aliases for friendly urls.
