Hi, I have two sites with 3750G's running OSPF connecting to a metro cloud. There are a number of other 3750G's in the same cloud also however only two are having problems. The Input queue is currently showing 1024/75/218/0. The result is that OSPF neighbor relationships are timing out. When I show the process's it is the PIM Process that is running at 99%. We are doing Multicast on the network which I assume this service is responsible for. All the switches working and non working are running 12.2(46)SE. Anybody have any idea's where to go from here?
