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.

Disabling nscd was the only reliable > workaround/fix. :( Thanks for the feedback. Any suggestions/experience with the system unreliability I'd seen after nscd crashed? Or does that improve if nscd is disabled entirely (instead of enabled but crashed, leaving a socket behind)?
