That's a relatively clear indication that the pcb list is corrupted. And below
you give the reason for this: you are accessing lwIP from the main task and
from interrupt level. I can only tell you again that this is NOT SUPPORTED. You
simply have to redesign your usage of lwIP to make sure it is not used at by
the main task and interrupt handlers at the same time!
