Too many open files when using port forwarding

[grossetti]

Hello,

Since VB doesn't allow ranges for port forwarding, I used a script that creates all the rules needed. When I start the virtual machine, I get this error now:

Failed to attach the USB device Chicony Electronics Co., Ltd. Integrated Camera [0854] to the virtual machine WinXP.

Failed to create a proxy device for the USB device. (Error: VERR_TOO_MANY_OPEN_FILES).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Console
Interface: IConsole {db7ab4ca-2a3f-4183-9243-c1208da92392}

This is quite blocking...it could be fixed if you had port ranges I think. I attached the logs and the script used.

Thanks, Gabriel

Logs, had to shorten them as you have a 512kb limit and the file was 3.2mb (the log file rotation limit)

Well, that definitely not bug in VirtualBox, perhaps it'd be better to alter file descriptors per process number in your host's OS system settings.
