I have also one box running a more recent r247539 or similar, but beyond that, things get really weird. As I reported, the problem isn't present in single user mode and seems to affect all of my systems which use nscd and OpenLDAP (this is standard (LDAP) in our environment). As pjd@ mentioned, things could be broken and I wait until the dust has seddled.
