Backing up a virtual machine with Changed Block Tracking (CBT) enabled fails after upgrading to or installing VMware ESXi 6.0 (2114076)
Description

Backing up a virtual machine with Changed Block Tracking (CBT) enabled fails after upgrading to or installing VMware ESXi 6.0 (2114076)
This will affect in vRanger when it is enabled
Cause

This issue occurs due to heap exhaustion. It can occur when attempting to enable Change Block Tracking (CBT). If a virtual machine with a large number of virtual disks reached an upper threshold, enabling CBT fails because of heap exhaustion. This issue also occurs with multiple virtual machines with CBT enabled. In case of Windows virtual machines with VSS enabled, taking a quiesced snapshot creates double the amount of memory overhead. Finally, if the heap is close to exhaustion, performing a vMotion can also cause this issue as that process involves taking snapshots as well.

Note: The virtual disks can be spread across virtual machines or can be in a single virtual machine.
