Maybe you'll find a bad PTR lookup or something. You can also determine if the stall is in NIS code with 'ypmatch userid passwd'. If nscd is running, does killing it make a difference? Any selinux violations in /var/log/messages? -------------- next part -------------- A non-text attachment was scrubbed...
