I try:
show mac address-table
show mac address-table <anything else>
The command just hangs on:
#sh mac address-table
Legend:
* - primary entry, G - Gateway MAC, (R) - Routed MAC
age - seconds since last seen,+ - primary entry using vPC Peer-Link
VLAN MAC Address Type age Secure NTFY Ports
------------+-----------------------+-------------+---------+-----------+--------+------------------
The secondary N7k does not have this issue.

Do you have a redundant/backup supervisor engine in the N7K?
If so, try to failover to it - I have had instances where the MAC address for a specific host has become "stuck" in one supervisor engine, and the only solution was to failover to the second engine and restart the first.
If you don't have a redundant engine, you may have to restart your supervisor engine with the "reload module x" command, or by simply restarting the switch. Note that if you've only got one supervisor module and you reload it, you will lose traffic while it reboots.
