some uncorrectables - Time Warner Internet

#1
This question is about "some uncorrectables", with Time Warner Cable internet and apps. I am getting a lot of uncorrectable errors on Downstream8 but none of the others. It's been going on for a couple-few months. I oly notice a little hang and slow down at times when loading web pages but would like to know why it happens and if there's anything that can be done about it. The table below is a day or so after a modem reboot. MAC address was deleted by me.
