Not if it is mirrored and replicated. Also nice if crashes are very rare, which they are unless you work at it.

I say it does not crash often, to the point where I have not seen it crash once for any reason I did not create myself (I tend to wait for the occasional brown bag release to fade away before shifting development We do get quite a few reports of less mature systems like hald and usb causing problems, and not too long ago NFS client was very crash happy. I did see some of those myself two years ago, and fixed them.
On the whole, Linux is very reliable. Very very reliable. Now mirror that, replicate it, add in 2 x 2 redundant power supplies backed by independent UPS units so you can do regular preemptive maintenance on the batteries, and you have a sweet enterprise transaction processing system. All set for a faster than light moon shot :-)
