Maintenance 11/20/2017 12:30-1:30PM

     We are going to be rebooting our physical host machines tonight to install a new kernel that addresses a copy-on-write exploit in the existing kernels.  The exploit can not be taken advantage of currently because nobody has access to the physical machines and we do not use KSM which consolidates memory pages because we have enough memory that it is not necessary.  At some point in the future however it may be so I want to address this issue and get it taken care of.

     Various services will be out of service for approximately 1/2 hour, not all at the same time.  If all goes well (sometimes it does not) we should be finished around 1:30AM.
