It almost never crashes for me now, but you might not be able to make the same claim. Well, if you use MyISAM rather than InnoDB you might be able to make the claim, but in that case you really need it to not crash as MyISAM might not recover to a transaction consistent state. The fix is not in the official release. This is almost a repeat of a recent post, but one thing has changed. We deployed the fix for bug 32149 and eliminated the cause of the majority of crashes from software bugs. We still get crashes on a daily basis, but hardware is the cause.
