i just did a little research for the badshare error on IOS 12.4(3) and it gave me the following
=========================================
CSCei27330
Symptoms: A router that is configured for Dynamic Multipoint VPN (DMVPN) may frequently generate the following error message:
%SYS-2-BADSHARE: Bad refcount in datagram_done
Conditions: This symptom is observed on a Cisco router such as a Cisco 871 and Cisco 1800 series that function as a DMVPN spoke.
Workaround: There is no workaround.
=============================================
my running config is as under..
