Subject Re: [MAJOR][BUG] ACS powers off some VMs in vSphere - when MS service is restarted
Date Sun, 29 Sep 2013 16:46:51 GMT
Ilya,
Can you check in the MS logs if more than one thread tries to process connect for the same
host simultaneously? In case of XS I had seen that there is a possibility of the vm states
getting incorrectly determined (during vm sync) in case more than one thread tries to process
connect to the host simultaneously. The fix for 4636 can be added to the 4.1.x branch but
if the root cause turns out to be the same.
