Peter, As this problem is "resolved" by removing either PIM or HSRP, it suggests it may be a resource problem rather than any specific process or ptotocol. When the OSPF adjacency expires what is the state of HSRP and PIM, i.e do they still maintain their neighbour relationships?
Also what happens if you do not mix IOS versions i.e. run either 12.1 or 12.2 on both routers? Regards, RB.
