Environment

VCD 10.x

Cause

This is observed when there are active sessions open for a longer duration of time.

This causes subsequent tasks to be queued and take more time to complete.

 

Resolution

Terminate any pending sessions that has been queued up for a longer duration. 

1. Refresh and reconnect the vCenter from VCD Refresh vCenter connection with VCD.

2. If the above does not resolve the issue, perform a rolling reboot of the VCD Cells, and this will close any open/active sessions.
