Hello,

I am running 2.6.18-274.17.1.el5 with openldap-2.3.43-12.el5_7.10.  Lately I've been seeing the following errors in /var/log/messages.  Once this error starts it appears to almost freeze the server.  I cannot connect via ssh and restarting services take minutes to restart if not restarting at all.  My only option is to reboot the server.  All is fine for a few days then it happens again.

nss_ldap: could not search LDAP server - Server is unavailable

This disconnects my samba shares and does not allow users to login to Windows anymore.

Can anyone help me with this issue?

Thanks for your time.
