A shot in the dark:
does
Code:
nslookup host

take a long time?
Perhaps it helps to trace your sshd:
Code:
strace `pgrep -P 1 -u 0 -x sshd`

Note down the function where it pauses.
If you have a quiet system, use strace -f to follow the child processes.

NAME
fence_drac5 - Fence agent for Dell DRAC CMC/5 DESCRIPTION
fence_drac5 is an I/O Fencing agent which can be used with the Dell Remote Access Card v5 or CMC (DRAC). This device provides remote access to controlling power to a server. It logs into the DRAC through the telnet/ssh interface of the card. By default, the telnet interface is not enabled. fence_drac5 accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_drac5 can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
