In my last post I was Exploring a Limitation of VMware DRS and I have encountered another situation that had similar symptoms but the resolution was quite different. This problem was occurring on a VMware ESX 3.5 cluster that was specifically affecting Windows 2008 R2 64bit virtual machines that were configured with four processors and eight gigabits of RAM. These virtual machines were taking an extreme amount of time to perform a reboot. During the reboot ESXTOP was showing insane %RDY with spikes climbing over 200. When the reboot would finally finish several services would have failed to start.
