KMC X 10 Chain - Popped a Quick Link

[Aushiker]

G'day
Yesterday, my KMC X 10 chain, which is fitted to my Giant CRX 1 and has down 2,479 km without trouble, popped its quick connection link yesterday, leaving me with an 8 km walk. There was no warning other than I have had a creak for some time but not sure if that is related to or not. I hadn't resolved this other issue but that is a different story.
Anyway, any thoughts on what might have caused this after so many kilometres? Suggestions on what to watch for to avoid this happening again?
Other relevant comments?

Hi Andrew,
Sorry to hear about your misfortune. It sounds too me like it was a defective link... I'm not sure what exact thing could have caused it.

Alex, I have now heard of one other rider with a similar issue with the KMC chain. Maybe they are not a good fit. Anyway will keep an eye on it and see how it goes.
I carry a spare SRAM link now
Thanks<br />
