Something is making libldap unhappy, which is being used by Ruby, used
in turn by Puppet. Which triggers the unfortunate error handling
behaviour of "abort the entire process now!!!" that I just *love* from
libraries I depend on.
So, I would go hunting for details about what causes that particular
assertion to fire in the LDAP library you are using. My guess would
be that there is a bug in there, tickled by some particular data set,
that those hosts hit, and that a newer release would probably fix it.
Other that turning off LDAP in the Puppet code, there isn't likely
much we can do about it.
