Incident
Report for Hosted Private Cloud
Resolved
We have noticed on multiple Private Clouds that some hosts have appeared \"not responding\" on vSphere for less than a minute.
There is no impact for the virtual machines on these hosts.
Only the operations on the virtual machines will fail during the disconnection.
We have identified that, at some point, the vCenter server is no longer able to open a TCP socket to communicate with the hosts.
We are investigating on the root cause.
Update(s):
Date: 2018-07-27 07:35:43 UTC
A windows update maintenance plan have been deployed to patch the issue.
If your vCenter is impacted, you can create a support request to apply the update as soon as possible.

According to Microsoft, the KB : KB4345424 (http://support.microsoft.com/help/4345424) fixes the issue.
We have approved on our WSUS servers, this patch will be applied on all new Windows Updates maintenances.

Looks like the windows update KB4338824 is causing this issue.

This behaviour has only been observed on vCenters where we applied the last Windows updates patches.
