On an HPE ProLiant server configured with any of the network adapters listed in the Scope section below, and running VMware ESXi 5.0/5.1 with bnx2x driver version 2.712.70.v50.3, VMware ESXi 5.5 with bnx2x driver version 2.712.70.v55.3 or VMware ESXi 6.0 with bnx2x driver version 2.712.70.v60.3, on a VXLAN Environment under significant load, the VMware ESXi hosts may lose Network Connectivity on networks where the bnx2x supports the interface. The following is an example of the content in the vmkernel log. The logs may vary in different environments: vmkernel: cpu2:33473)<3>bnx2x: [bnx2x_panic_dump:1396(vmnic6)]Idle check (1st round) vmkernel: <5>[bnx2x_self_test_log:149(vmnic6)]INFO CFC: AC is neither 0 nor 2 on connType 0 (ETH).
