serious bug, reproducible lockup 2.9.41

I can easily cause my RouterBoard133 with version 2.9.41 to lock up so bad that it must be power cycled to fix.

Put PPTP client on 1 interface.

Put Hotspot with rate-limit onto another interface.

Turn on PPTP Server.

Connect to remote PPTP server.

Connect THROUGH the hotspot to the PPTP server

Start transferring files from a computer on this network to the remote network over the PPTP Client.

The router locks up EVERY SINGLE time I do this. I can not even MAC-Telnet or MAC-Winbox into it.

If I remove the hotspot, it works fine, except for occasional random lock ups (Except I would like to be able to use the hotspot this way)

Can anyone else reproduce this?

Thanks,

I have the same trouble, with later firmware. Not sure what to do. It happens with all my RB100 series products, but not the 500 series.
