Symptoms:
During the normal VMware Consolidated Backup (VCB) operation, the VMware Tools status changes from OK to Not Running for some time during the initial snapshot operation, but it returns to OK after the VCB operation completes.
However, on hosts installed with the patch bundle ESX350-200901401-SG, the VMware Tools status on the virtual machines may stay as Not Running even after the VCB operation completes.
