When this happened to us on our linux hosts, I found that I needed the 
Name Service Cache Daemon (ncsd).
So, I have this daemon running on linux and all is well now. 
This is normally needed if you have a slow naming service.
I can't remember when this problem started; I wish we did not depend on 
this ncsd.
