Is ColdFusion on Linux/Apache stable?
It's perfectly stable. I ran a hosting company with ColdFusion 4 through 6.1 running first on Fedora and later CentOS. I used to work for Nationwide and deployed a major application there using ColdFusion 6.1 and later 7 of Red Hat ES.
I've written an extensive article on what you'll run into when moving a ColdFusion application from Windows to Linux.
You can find more info about running ColdFusion on Linux here or by searching ColdFusionBloggers.org.
Absolutely (32bit and 64bit) - you can see a list of officially supported platforms on the Adobe site:http://www.adobe.com/products/coldfusion/systemreqs/
Linux OS:
Red Hat Enterprise Linux 5.3SUSE Linux Enterprise Server 10.3Ubuntu 9.04
Apache HTTP Server 2.0.63 and later
I have had absolutely no problem ever running Coldfusion on Apache on linux.
In fact, I had a windows NT 3.51 server running Apache (for windows) beta for several years, with Coldfusion 4.5. Zero issues.
The server still runs and I only turned it off because it was outdated.
