I concur. We've been doing stress testing of our vSphere 5.5 support code for the past few weeks, and we've seen plenty of PSODs with ESXi 5.5 under heavy load... it is prone to crashing like no other ESXi version before. I like to say, Windows Vista was solid as a rock comparing to ESXi 5.5 (and this says a lot).donativo wrote:It canceled and failed over to network mode. In exactly this second the whole ESX gives me a purple screen of death! I thought it was just an error. Tried again, and it happened again just in this second where it failed over to network mode. So something is really not working there.
Of course, we are using all the same hosts that were previously running older ESXi versions, and those were solid. So, things are not looking good for ESXi 5.5.
We have some ideas on what specifically is causing this, confirming them right now by eliminating a suspect from the equation, and will be opening a support case with VMware soon.
P.S. Specifically regarding hot add not working, this is the known interoperability issue between vSphere 5.5 and VDDK 5.1 that is resolved in VDDK 5.5.
