SNMP on Nexus 5548 Failing

The version on nexus is 5.0(3)N2(1)
It looks to me that snmp had been hanged for a while
dcassw202# sh processes cpu sort
PID Runtime(ms) Invoked uSecs 1Sec Process
----- ----------- -------- ----- ------ -----------
4565 1308 3838622539 0 46.5% snmpd
4681 184 90 2045 5.0% netstack
4476 1054 14064363 0 1.0% pfma

Any suggestions will be greatly appreciated.

This is a known bug and here is the workaround:
Unload the BRIDGE-MIB from the switch by using snmp server commands. If the switch is reloaded you will have to redo step 1 as this command is not persistent. For detailed information on the workaround please contact Cisco TAC.

Also remember disabling SNMP will not fix this problem, you have to unload the BRIDGE-MIB to free up the memory. However, per the bug's release note, this information needs to come from TAC only.
