I had been running a plot with 5 hops every 5 seconds for about 88 hours and had accumulated 63,120 samples. I stopped the plot, saved it, and went to work.<br><br>About 8 hours later I loaded and resumed the plot. After a few pings PP went CPU bound and remained that way for a couple of minutes. Beyond that, resumption of the plot seemed normal. <br><br>This problem is reproducible by reloading the PP2 file. It's possible PP goes CPU bound on the first failed ping as once I pinged for a good minute or so before it happened. (the line I'm monitoring has a 20% dropout rate that the Telco is working on).<br><br><br>
