Hi.

The vpx process was crashing with the following error in /storage/log/vmware/vpx/vpxd.log

Repeat for every DVS, with different DVS_ID.

After import of DVS settings (only thing that comes to mind that could have caused this, since the VCSA is a new installation, but DVS were imported from previous vCenter instance), the values in port_counter column in table VPX_DVS were zero instead of the correct value.
When creating a new port (e.g. when creating a new portgroup with static binding), vpxd picks too-small port numbers for new ports. Those number are already in use in VPX_DVPORT_MEMBERSHIP and cause primary key violation.
