That would surprise me, given how robust Earth life already has to be. I mean, it wasn't fun, but Earth "sustained life" through several massive volcanic events, giant meteors, and climatic changes, to say nothing of magnetic pole reversals, et al. It seems that once life gets going, it can tolerate a lot of crap.

That is, just because a planet can sustain life doesn't mean that planet's history would generate life. There may be a gazillion earth-like planets, but that doesn't mean life is possible on that attribute alone.
