Windows Server KB4520005 causes Issues with Veeam
Had a client call today with a windows server vm issue. The vm was the primary Veeam backup server. The client was noticing the server lockup for 10 to 15 seconds at a time. This was happening about every 15 min. while troubleshooting the event logs we ran across this error
After looking into the windows updates recently applied I noticed that KB4520005 was a storage subsystem update for windows. This VM uses the vmware paravirtual adapter as its SCSI controller. I removed the KB in question from the server and rebooted. All the pause issues went away. Please be aware of this while patching your windows servers. The server in question is a Windows Server 2016 server.
