OVF Deployment is failing with error Read timed out" while deploying VM in vSphere Web Client

Products

• VMware vCenter Server
• VMware vSphere ESXi

Issue/Introduction

Symptoms:

When deploying the OVF from VC the deployment fails with error: 

Encountered error "java.net.SocketTimeoutException: Read timed out"

Environment

VMware vCenter Server 6.x
VMware vSphere ESXi 6.x

Cause

• SDRS has a limitation that only one task can run at a time on a given datastore cluster. One of the task took more than 30 minutes to complete and because of this, the subsequent tasks keep on waiting for the previous tasks to complete.
• The OVF deployment task was initiated when the SDRS load balance task was in progress, and it will continue to wait until the current running task is completed. But the content-library code is responsible for the ovf deployment. It is likely to have a shorter timeout value than it takes for SDRS to give a recommendation. Hence the task fails.
• In /var/log/vmware/vpxd/vpxd.log, you can observe that the SDRS recommendation is being executed repeatedly. For this instance, it was being executed every 30 minutes.
