Cause

On 7.0 GA host, the "esxupdate" memory resource pool used for baseline check compliance is too small to handle all ESXi patches/updates that have been released to date

Resolution

The issue is not seen on ESXi hosts running 7.0 U1 and later due to increased memory allocation

Options for upgrading the ESXi hosts:

1. Upgrade the ESXi host via the ESXCLI method

2. Use vLCM ISO upgrade baseline to upgrade the ESXi host to a later version

3. Least recommended option - Revert vCenter back to the 7.0 release line and perform patching first to upgrade the host to a later 7.0 version
