savecore fails to tell fmd when crashdumps fail
cmd - userland programs
savecore: System dump time: Tue Sep 6 17:42:06 2011 savecore: not enough space in . (2539 MB avail, 4235 MB needed) savecore: bad summary magic 781b3834 savecore: failed to publish 'savecore_failure' event: Library API usage violation
The last two lines there represent bugs, actually, since obviously the magic is fine too.
I'm guessing this relates to causing savecore to return failure.
