The saddle for that string is quite high now and I'm concerned it's applying too much pressure in that area. Could be prone to snap. Mind you, I don't know how high is too high. I don't know what the fretboard curve is?[/quote]
Chris May (of overwater) describes it perfectly, a bass neck is not straight, but should be "ski" shaped. That is to say that around the 7th fret it starts ever so slightly bending inwards, towards the strings. A good way of measuring this bend is to hold down the string at the first and last fret and then seeing how big a gap there is under the string at the 12th fret. Ideally it should be around a mm (ish!).
How far away the strings are from the neck normally is totally down to personal preference, and is subject to change when you tweak the neck, so experiment with the bridge saddles and see what is comfortable. You can't really do any damage here but do watch your intonation - If you want an explaination of what that is then just ask!
