seeing as fedora is a testing and R&D distro it is likely to crash A LOT .
Even on a perfect install gnome or kde WILL crash xorg -- no if's ands or buts -

X will crash from time to time
?? never found a need for it
And i would NEVER put Fedora on a production server
the 13 month life span is WAY,WAY,WAY to short
UNLESS you DO LIKE ( and have the TIME to) reinstalling a server every 6 months when a new version of fedora is released

but if you WANT to do that -- go for it, I would not.

Just look at the list of supported operating systems from the source:

If you are looking to stick with a Red Hat derived OS that is free I would go with CentOS, which is basically the same as RHEL without support, or branding. As mentioned Fedora is a very cutting edge OS, and thus not necessarily the most stable. It also has a very short lifecycle, another thing not too good for a server OS.

Can you please stop spreading this FUD, Fedora is a stable distro and is not "likely to crash A LOT". Maybe older releases this was the case, but not within the last couple of years.

Again, I'm not trying to be a jerk, but you keep saying this and I'd hate for people to get the wrong idea about Fedora.

I agree, there are better alternatives to Fedora if you need a production server, mainly due to the short lifecycle.

i am a LONG TIME user of fedora and it is not FUD

fedora's philosophy is to push the envelope until it brakes , this is fine but is not good for a server

would you run a FMRI using fedora ?? -- i think not

would you run the NYSE on Fedora , and reinstall the software on the NYSE every 6 months when a new version is out ? - i think not .

would i run a home system on fedora - yes

i might also run a small office ( IT ) 6 person office - with a full nightly back up
-- this is debatable -- i might or might not - suse or debain would be better choice .

I already answered those questions and I said that I would not use it as a server, I agree with you there. In my first response to you I even said "I would not recommend using Fedora as a server." However, you keep saying that it's not stable and it crashes a lot. Like I said, 3 times now, that was the case with older releases, but since at least Fedora 11 it's been very stable.

I upgraded from Fedora 12 to 13 when the alpha version was released, even the alpha version was incredibly stable. How often have you had Fedora 12 or Fedora 13 crash on you?

Thank you very much everyone
I am installing on my server red hat operating system
I cant really go on UBUNTU, CentOS
since my website software would not be compatible to that operating system and they are only compatible for Linux.

CentOS and Ubuntu are both Linux distros, just the same as Fedora. Also CentOS is not only a Linux OS, but is also a Red Hat based distribution. As I mentioned in my prior post CentOS is basically Red Hat Enterprise without support. "Red Hat" will basically fall into three main actual distributions, Fedora (cutting edge), CentOS, and Red Hat Enterprise Linux (RHEL).

So if you are saying you purchased or plan to purchase a RHEL subscription, great. Otherwise use CentOS (it is listed on the supported OS page for Plesk), unless there is some other software that you need to run. If that is the case maybe it is best to post your full requirements.
