There are a lot of things that can influence reliability:
Computer:
model and O/S
amount of RAM (more is better, of course)
HD speed (7200 rpm / 8 or 16MB cache is better)
stability of drivers for audio and MIDI interfaces
System settings such as processor idling/networking/virus scanning etc. (turn them off)
Live related:
stability of VSTs and VSTi's
size of Live set (total size of clips / total CPU draw of plugins)
no. of clips played simultaneously (i.e. disk load)
Other factors:
Too much MIDI sent from controllers can choke Live/OS/drivers/interface
Stability of the AC supply
HEAT!!!!
HUMIDITY!!!!
VIBRATION!!!
Out-of-it punter (stage invasion)
...and a little thing called operator error
The thing to do is get your set as you want it for gigging and then torture-test it to destruction: find out the limits of the no. of clips you can play simultaneously, the maximum no. of plugins etc. If you are using a MIDI controller, play stupid amounts of keys/knobs and try to make it crash.
Once you have your system stable, LEAVE IT!!!! No OS updates, RAM expansions, software installs, or new bits of kit just prior to the gig - you'd be amazed how many people I've seen get bitten by this - me included!
Tips: Render as many CPU-hungry FX as you can into audio, especially reverbs.
Make submixes of multiple tracks into one track where possible.
Remove un-needed VST's and VSTi's from your VST folder for gigging.(just have a second, minimal VST folder for gigging)
Try to keep your CPU load in the 60 - 70% range if possible
Take for granted that your computer WILL crash sometime, they just do, get used to it, and have some kind of emergency plan to get you thru while you re-boot. A CD/MD/vinyl/iPod/cassette/anything cued up.
We use 2 laptops on stage (one plays bass and drums, the other the instruments). Each laptop has a muted track playing a ruffmix of what the other computer is doing for any given scene. If one machine goes down we can un-mute this track and "fly on one engine" while re-booting the other lappie with a minimum of grief.
