[En-Nut-Discussion] Up/down interface, heap

[Szemző András]

Hi,

I can connect to GPRS with PPP interface, and I can terminate the link (with
closing the PPP interface, It disconnects ok), 
I can setup it again without reboot, and terminate, so on...
The only problem is as I see the heap is continuosly decreasing...

What may be the problem? 
(I now removed all my malloc/free in my program, so I think the problem is
in the NUT)

Thanks
Andras
