Unable to initialize usb library (-99)

Hello,

does anybody happen to know what does this error message mean?

I deployed:

vSBC-AMS# show ver

Acme Packet Net-Net OS VM SCZ7.2.9 GA (Build 83) Oracle Linux branches-7/el7-u1 {2015-03-20T07:00:00+0000} Build Date=04/28/15

and this message appears every few minutes in the VM console window. It is not visible in the ssh shell.

The SBC is not configured yet, so the impact of the problem cannot be evaluated, but I cannot migrate traffic to it before I'm not 100% sure what it means and why it is reported.

I noticed that there are hundreds of files in /mnt/huge2m/ directory. The name is oracusbcmap_XXX and the number number of files keeps growing...
