A custom bug ID has been generated as the vendor did not provide one: e0c52788e504
If you do not set the supported_num_ports module parameter for the nmlx5_core driver on an ESXi host with multiple network adapters of versions Mellanox ConnectX-4, Mellanox ConnectX-5 and Mellanox ConnectX-6, the driver might not allocate sufficient memory for operating all the NIC ports for the host. As a result, you might experience network loss or ESXi host failure with purple diagnostic screen, or both.
Set the supported_num_ports module parameter value in the nmlx5_core network driver equal to the total number of Mellanox ConnectX-4, Mellanox ConnectX-5 and Mellanox ConnectX-6 network adapter ports on the ESXi host.
