nscd: nss_ldap: reconnected to LDAP server errors RHEL 5.4

I'm a network services rookie and I am seeing this error, but it doesn't seem to be effecting functionality.

Nov 22 12:12:16 r01 nscd: nss_ldap: reconnected to LDAP server ldap:// after 1 attempt

This error is scattered through out my logs. We are authenticating this Red Hat server to another OpenLdap server. Everything seems to work just fine and we are not even using Kerberos as this is a render server. We set-up ldap right in the GUI, nothing fancy.

RHEL 5.4, Basic install, again, nothing fancy. LDAP does seem to be working fine and allows the right people to login to the machine.

We have two of these machines running and both are configured exactly the same and getting the same errors.

This error ring a bell with anyone?

It totally rings a bell, yes. I think it's an issue around file descriptors being used up in that version of nscd. Upgrade it and I think you're fine. We definitely had this problem, but I'm a little rusty remember the root cause from cold right now. It might sound a little naive, but the benefits of nscd can be very marginal when it does work, so maybe you'd not be any worse off just disabling it altogether. As for finding out if it is using up file descriptors, see what lsof says about it's file usage, default max per process would be 1024, and a working version of nsvd should be nowhere near that ever.

Yeah, I found another thread about not needing nscd, I think I will try that and see if that helps any. Thanks Acid.
