Follow-up Comment #17:

OK now I see: you're probably coming from a uIP world where you don't want to
allocate 10 KByte for the IP stack? In lwIP, this is rather little memory,
given that you allocate *all* memory from the heap, even all RX pbufs!

Are you sure that your PBUF_POOL_BUFSIZE is set to around 127?

Anyway, this is not a 6lowpan issue but rather a question "why does lwIP
consume more memory than I would think it would?"

By tracing the calls to mem_malloc(), you should find out...

I'm closing this, as you said the crash (which is what this bug is about,
after all) might probably be in your driver.
