Hi folks,

I have a bridge that containes of 2 Ethernet interfaces. When using
nttcp to test the throughput of the bridge, the kernel will use more
and more memory. This way, all available memory will be used after a
few thousand packets and I get a lousy performance and the bridge
function is very stagnant. I can see a large amount (up to 5000) of
4096 byte buffers allocated in /proc/slabinfo (the size-4096 line). I
don't see a reason why a bridge should be that memory hungry, so I
think that there is a memory leak somewhere. Is this a known behaviour?
The kernel version is 2.4.18, which is the latest version available for
this hardware (ARM based embedded system).

Regards,
Tino
