Environment

VMware vCenter Server 5.5.x
VMware vCenter Server 5.1.x
VMware vCenter Server 6.0.x

Cause

This issue may occur when there is resource contention with the vCenter Server (low CPU/RAM or slow performing disk I/O). Because of this, the kernel service waits for the Application indefinitely causing an unavailability of the kernel service to the user region.

Resolution

To resolve this issue, check if the server resources match the minimum requirements for installing the VMware Web Client. For more information, see Minimum requirements for installing the vSphere and vSphere Web 5.x Client (2005083).

If the server resources do not match the requirement:

1. Increase RAM, CPU, and Disk size.
2. Restart the VMware VirtualCenter Server service.

Additional Information
