Looking at this some more, the only way to call write_to_net_io from NetHandler::process_ready_list is for the VC's write.enabled and write.triggered be non-zero.
Looking a the dump of the VC this is not the case. It looks like another thread is either freeing the VC on you or something is overwriting memory.
