Is memory utilization of 88% considered excessive ? It seems fairly stable at that level . Seems to vary up and down a little so it appears it is freeing memeory when it doesn't need it. We get monthly Vitalnet reports and this one seems to be on it all the time . It is a 6 stack 3750 setup running 12.2.35 SE1. Could not find anything in CCO that really pertained to what I'm seeing . Switchport utilization on the ports them selves is extremely low , fabric utilization is less than 1% .
