It's really only as stable as your hardware is. Our web servers as a whole are primarily 64-bit CentOS (some older RHEL 3/4 32/64bit systems too), serve about 2 billion requests a day. The only stability issues are many of the older systems are..old(most are 3-4 years old), sometimes they crash. We're 1/3rd the way through replacing all of the older gear with new stuff though and cutting the # of systems by a good chunk. If you want a stable system just be sure to get stable hardware, HP and IBM seem to be the best as far as being bulletproof(as you can get for x86). Dell's quality on the other hand is significantly lower(primarily due to their built to order model and sourcing parts from multiple vendors with lacking quality controls, cheaper prices but you get what you pay for). And of course the various whitebox vendors out there have varying levels of quality control. But stability of the OS itself, provided you stick to the base install and don't install 3rd party kernel modules, stay away from 3rd party repositories unless you really know what you are doing, your system will be as stable as the hardware it runs on. The new HP DL165G6 systems seem like great little (cheap)web servers, I should have one soon to test, though I'd still prefer a DL385G6. Most of what we run today is Dell(just got 40 new R610s), though that sounds like it will be changing(yay). nate _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
