We changed the direction. Unlike with previous upgrades we hope to be
able to reduce memory usage in newer versions. ;-)

I'm not sure that this is network related. After upgrading, you are now
able to dump heap usage.
Add
HWDEF+=-DNUTDEBUG_HEAP
to UserConf.mk (build and app tree) and rebuild everything. At specific
locations within your application call
NutHeapDump(<file-pointer>);
replacing <file-pointer> with your console stream, probably stdout.
You'll get a list of all allocated fragments, which will help to locate
the memory hole.
