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.

I've had problems with nscd crashing every few days on my CentOS 4 mail server for a while now. The problems started maybe around CentOS 4.2, although I don't remember for sure. My debugging efforts let me to disable nscd's persistent cache, and that seemed to work for a while, but since upgrading to CentOS 4.4, the crashes have started again.

Has anyone seen similar problems with nscd?
Yup, another me-too. 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)?
