issue "show proc mem <pid>" (where <pid> is the process id of the IP
Input process) a couple of hours apart and check which PC(s) show an
increasing number. Please post the result along with a "show version". 
IP Input handles packets to the CPU. Does "show proc cpu" show high
utilization in the input process?
