[Arm-dev] Centos 7.9 weird firewall/application issue

Hello,

I have a weird  issue with the firewall running (Centos 7.9) wit an application.

The application pulls data from an Ad-converter card, via USB, and  sends the data to a db server using curl. (via a wireless device that is plugged into USB.

When the firewall is running I get all kinds of weird errors (in that application), usb-port related BUT when the firewall is not running, it works just fine.

(I wonder if it is a memory issue?)

any ideas here?

thanks,

Ron
