I'm starting to have this problem as well. I have two mail servers running courier and postfix. They've been up for a couple weeks but I just put them into production monday this week, two days ago.

The first time it had happened, I was using the stock /etc/nscd.conf file. The second time it happened on the other server, I had doubled the max-db-size passwd value to 67108864.
Both servers are running CentOS 5, firewall disabled and no SELinux .

The two previous servers did not have this particular problem. They were not identical hardware, but identical os install and config,
Any clues?
