Apache sleeping when inactive

Hi All,

I'm currently working on a website which runs on a LAMP system (linux, apache, mysql & php). The web hosting company appears to have configured apache to "sleep" when it's been inactive for N minutes... however I can't find how they've done it. I would like to disable this sleep as the web site doesn't have that much traffic so it's effictively slowing down the first http request for each user.

Any ideas where they've set this up? I'm hoping that it's not a configuration set outside the virtual server (i.e: where I can't access!)

This is not possibly done on apache.  No way - it is a SERVER, which means, it will be serving.  HTTPD stands for "HTTP Daemon" - daemons usually do not go to sleep, but it really negates the idea of running a service and making it sleep.  If a daemon stops responding - it means something is wrong.  If it is Micro$oft, heh, no guarantees regarding anything! All bets are off!.

I am guessing that it is the server that is going to sleep or having issues, but not apache unless they blew the performance tuning MAJORLY.   Check process prioritization, how many processes are running, and what is in the error logs..  

How to know if apache can "sleep" or not - search google (apache sleep).  You will get only a couple rseults, but the most informative would be:
http://httpd.apache.org/docs-2.0/misc/perf-tuning.html
If you read thru this, it will explain how the server handles requests.

Ack I forgot I had this Q open - I spoke to the web hosting company - apparently the web site doesn't have a static IP addy and the way they deal with it forces the apache daemons to sleep while inactive. Sounds completely pointless to me, everytime it sleeps googlebot or similar wakes it - it's just adding a few milliseconds to the load time - frustrating!

Anyway, I'm getting a static IP for the site which they have assured me will stop the sleeping.

I know it's not particularly correct to award you the points - but I can't be bothered posting in CS =P
