Symptom
vlan_mgr generates a core file with signal 11 when fetching data from invalid memory address.
Conditions
Nexus switch crashes while issuing "show vlan internal mapping". So a crash in vlan_mgr is see after this:
%SYSMGR-2-SERVICE_CRASHED: Service "vlan_mgr" (PID 7957) hasn't caught signal 11 (core will be saved).
%CALLHOME-2-EVENT: SW_CRASH vlan_mgr in slot 27 crashed with crash type : stateful crash
