I just had a quick question.
How big of a chance is there that a server will be overloaded, leading to a unreasonable ammount of downtime?
Let's say I pay about 8 dollars for shared hosting. With unreasonable ammount of downtime, I would say that a half hour a day is really unreasonable. Actually, I would say that downtime more than 10 minutes a day is unreasonable. Is it unreasonable, or am I unreasonable? If so, how much downtime should one expect?
I have a X3220 server with 4GB RAM.
OS is CentOS5.3 - 2.6.18-128.1.6.el5PAE
I tried to optimize system, but the RAM usage is just around 1.5GB with high CPU.

I wonder why system uses around 1.5GB RAM only? How to put more data into RAM? This server is serving for a high traffic site. From apache status

how I can get rid of this?

After a reboot the networkscripts did not start properly. My Dc fixed/changed some things so named could start again.
Now my secondary ip has not been loaded (using directadmin btw).
What could have gone wrong, and how to fix it?
I don't really dare to reboot, because i can't get it online when named doesn't start (i have to call the dc again etc).
My logs showed this:
Directadmin log

How can I arrange so stats are not loaded?
IMPORTANT: Do not ignore this email.
This is cPanel stats runner on server.dealsreferals.com!
While processing the log files for user stnudee, the cpu has been maxed out for more than a 6 hour period. The current load/uptime line on the server at the time of this email is
09:35:21 up 6 days, 22:32, 0 users, load average: 2.76, 19.13, 52.20
You should check the server to see why the load is so high and take steps to lower the load. If you want stats to continue to run even with a high load; Edit /var/cpanel/cpanel.config and change extracpus to a number larger then 0 (run /usr/local/cpanel/startup afterwards to pickup the changes).
just bought a script from filerun, try to load it

but .php file cant be encoded, any help would be nice.

I have a server that keeps dying on my mysteriously. I've loaded it with Windows 2003 and Linux. Both crash about once every other day. So I'm guessing this isn't a software issue, but a hardware one.
When it crashes the screen turns blank. Only a hardware reboot will work. The power doesn't go off though.
Anybody here experience something like this before? I'm guessing it's one of the following:Power supply
CPU
Motherboard
However I'm thinking it's probably not the power supply as the server is relatively idle. I did stress test the server and it didn't crash then.
The thing is, there are no event logs from the BIOS or anything.

Using a cpanel/centos box with mysql 5 and php 5
I have the follow errors at (one) of my plesk panel:

We use Plesk 12 with ubuntu 12.04.5 LTS ......
Plesk 12 does not create backups for Customers.
If we restarts the server, Plesk created again for 2 days backups and then again not. There are no errors present.
The backup should be loaded on a FTP backup server after the Create
This makes Plesk but only if you restarts the server. Otherwise, no backups are created or loaded on the FTP backup server.....

any hints for EXIM reject E-mail trying to be sent to an non-existent account on a domain hosted by me? I think the default configuration is to accept the E-mails and try to deliver, then it will fail and an E-mail will be sent to the sender
but many times the sender is fake (spammer) and this message will rest on queue for some days...
I was thinking on some filter like
"if ((!exist account@domain) && (!catchall domain)) reject"
but I don't know how to set something like that on EXIM
I am running Apache on a Windows server and it is up and running.I downloaded and installed:
Apache 2.4.9 Win32 [Apache VC11 Binary] httpd-2.4.9-win32-VC11.zip
And included ModSecurity from download: modules-2.4-win32-VC11.zip..
The version of ModSecurity is mod_security-2.7.7 . It is up and running, but I get a warning:
ModSecurity: Loaded PCRE do not match with compiled!
Here's the difference in the PCRE from the logs:
PCRE compiled version="8.33 "; loaded version="8.34 2013-12-15".
The compiled version does not match the loaded version. Is this something I should be concerned about and try to find compiled versions that match?
