      I have some warnings and errors in the event viewer that I'm going through now. Is there any reason to have IPv6 enabled if we're not using it? A lot of warnings in there about IP6 supposed to be static only.

      Don't think so. It is often disabled for performance reasons. "Often" meaning, it's not uncommon, not meaning "normally."

        @scottalanmiller I read that IPv6 was used by some windows system services and that disabling it would slow the system. Did I misunderstand the article or was it just wrong?

          Is that in 2012 R2, or more recently in 2016?

            @scottalanmiller That could be the part I missed. I will have to find the article again and get back to you. Thanks.

              @popester It was an older article on 2012 R2. It appears that the problems created by disabling IPv6 are growing with Server 2016. This may become a "prison sex" scenario.

                I'm not familiar with how that term applies here (or anywhere other than when talking about sex.)

                  @scottalanmiller You can only put off IPv6 for so long. Eventually you will be assimilated. No pun intended.

                    My reference was very unprofessional and I would like to apologize to the group. I will refrain from such sophomoric behavior in the future. This is not the venue for such things. Thank you.

                      Do you have the latest Xen-Server tools install on your VM?

                        We are all sophomoric here. Just wasn’t sure how to apply the reference to the situation.

                          I’m testing quotes again.

                              No, looks like that was pretty old. I just updated and restarted. I'll monitor the memory for a while and see if that has any impact.

                                Odd question, why are you keeping snapshots for a week at time?

                                As for the leak, you mentioned the azure change and noticed this issue.

                                So what is pointing you to this as the possible issue?

                                  I wouldn't disable ipv6 unless you are unable to find and fix the real root cause of an issue in which disabling ipv6 may mask.
