This issue is resolved in a patch release for ESX/ESXi 4.1. For more information, see: ESX 4.1 – VMware ESX 4.1 Patch ESX410-201011401-BG: Updates vmware-esx-drivers-net-bnx2x (1029394) ESXi 4.1 – VMware ESXi 4.1 Patch ESXi410-201011401-BG: Updates Firmware (1029398) This issue is also resolved in the asynchronous Broadcom driver release bnx2x 1.60.50.v40.3 and newer. For more information, see VMware ESX/ESXi 4.0 Driver CD for Broadcom NetXtreme II BCM57710, BCM57711, BCM57711E Ethernet Controller and How to install async drivers on ESX/ESXi 4.x (1032936). This issue is also seen with the 4.1 U3 inbox driver version 1.54.1.v41.1-2vmw. See, Download VMware ESX/ESXi 4.x Driver CD and HP Download drivers and software.
To determine the version of the installed driver: Open a console to the ESX or ESXi host. For more information, see Unable to connect to an ESX host using Secure Shell (SSH) (1003807) or Using Tech Support Mode in ESXi 4.1 (1017910). Determine the version of the bnx2x driver using the command:vmkload_mod -s bnx2x | grep Version Note: If this command returns no version number, the bnx2x driver is not in use on the ESX/ESXi server and this issue is not applicable.Using Tech Support Mode in ESXi 4.1, ESXi 5.x, and ESXi 6.xVMware ESX 4.1 Patch ESX410-201011401-BG: Updates vmware-esx-drivers-net-bnx2xVMware ESXi 4.1 Patch ESXi410-201011401-BG: Updates FirmwareInstalling async drivers on ESXi 4.x and ESX 4.xBroadcom bnx2x（筐体内ドライバ バージョン 1.54.1.v41.1-1vmw）を使用した VMware ESX/ESXi 4.1 ホストでネットワーク接続が失われ、紫色の診断画面が表示される具有 Broadcom bnx2x（内置驱动程序版本 1.54.1.v41.1-1vmw）的 VMware ESX/ESXi 4.1 主机出现网络连接丢失并显示紫色诊断屏幕
