I add to the list that NSCD in Centos 4.4 fully updated crashes every
hour or so (this is a 5000+ email per hour mailserver with rbls,
antispam and the whole enchilada)

The only entry i get is :
nscd: 2472 invalid persistent database file "/var/db/nscd/hosts": file
size does not match

So i disabled nscd. Problem fixed, no more horrible crashes from
sendmail+rbl lists. I wont even bother to dig deeper, I cant do it in
my production server.

When a new release of nscd arrives or if maybe i can test it in a
non-heavyloaded mailserver, then i'll try it again....

nscd: you served well my friend (in 2.4 kernels)...but not anymore. R.I.P.
