VirtualBox guest OpenWrt OS crashed when using the nmap to scan the wireless network through the USB port

[MercyLin]

Guest OpenWrt OS crashed with the following configuration and operation Host is the Lenovo ThinkCentre M920t desktop PC, WIN 10 professional OS. The VirtualBox v6.1.12 with extension pack 6.1.12 is installed. The Guest OS is Linux 64bit(OpenWrt Lede 17.01). Using the MediaTek USB wifi dongle MT7601U to act as a AP(AccessPoint). It works well, I can connct it by my mobile phone and surf the Internet without problem, but it will be crashed once I use the nmap(v7.31) to scan the wifi network. I have the exactly same configuration with my HP laptop and the sympton won't happen in it, don't why it's crashed with my Lenovo desktop PC.

Hi, What does it mean ? May I have more comment from you ?

Change the different nmap arguments can solve the issue, case closed
