Hi !
We are curently deploying an 8 nodes cluster where we have a RHEL 6 license
at great costs (~14 k$/y). It will be our new production environment for
mission-critical services.
Now our aging developpement server (old p4 with 1.5 gig of ram) need to be
updated. We will be installing on hard

Hi !
Since the last couple of months, we had a few problems with the maner we

On another note, on the same subject (xServes being disontinued), one
feature we use heavily on our os-x server is the ability to load / unload
periodic jobs with launchd.
With it we're able to schedule jobs let's say every 5 minutes, and so on.

Bonjour Robert.
From experience with this kind of problems, you need to check what script (php
or other) is served by that process at the moment it takes that much ram.
The first thing you need to look is was the httpd process is responding to. If
it's not, switch the ExtendedStatus to on, and
Also, a thing I've notice is that httpd process tend not to relase it's used
memory very fast. So if you see that the process is not doing much (via
server-status), you can safely kill it. The parent httpd process will create a
new one when needed.
