Performance/Stability issues when using View 5.1.2 Agent on physical machine based desktops
To work around this issue if you use VMware View to access physical machine desktops:
- Upgrade your Connection Servers and Security Servers to VMware View 5.1.2 immediately to get the latest functional Security fixes. To download this version, see the VMware View download center.
- Do not upgrade the VMware View Agents as part of the upgrade; keep your View Agents at version 5.1.1.
Note: If you do not use VMware View to access physical machine based desktops, no workaround is required. VMware will support the prolonged mixed use of View 5.1.1 Agents with View 5.1.2 Connection Servers and Security Servers until such time that a fix to the physical machine based desktop incompatibility becomes available.
