Environment

VMware vCenter Server 6.7.x
VMware vCenter Server Appliance 6.7.x

Cause

The vpxd service might fail when the vSphere Storage DRS provides an initial placement operation. One of the internal data structures in vSphere Storage DRS initial placement workflow might be overwritten with a NULL value, which might result in a null pointer reference and a vpxd service failure.
