To resolve the Pool is shut down error when logging in to the vSphere Web Client, restart the vSphere Web Client services.

When using VMware vRealize Operations in your environment, you experience these symptoms when logging into the vSphere Web Client:
  • You see the error:

    A server error occurred.

    [400] An error occurred while processing the authentication response from the vCenter Single Sign-On server.

    Details: Pool is shut down...

    Check the vSphere Web Client server logs for details.

  • In the C:\ProgramData\vCenterServer\logs\vsphere-client\logs\vsphere_client_virgo.log file, you see entries similar to:

    [2015-07-24T11:15:30.877-05:00] [ERROR] http-bio-9443-exec-31 70005834 100021 200006 com.vmware.vsphere.client.security.VimAuthenticationHandler Connection failure to vc https://web_client_server:443/sdk java.util.concurrent.RejectedExecutionException: Pool is shut down.

VMware vCenter Server 6.0.x
VMware vCenter Server Appliance 6.0.x


This issue can occur due to the Management Pack for Storage Devices (MPSD) that VMware vRealize Operations utilizes.


This issue is resolved in vCenter Server 6.5.x, available at VMware Downloads.
To work around this issue in previous versions, restart the VMware vSphere Web Client services.

Note: If you have more than one VMware vCenter Server, you must restart the VMware vSphere Web Client service on all VMware vCenter Servers in the Enhanced Linked Mode group.
