It seems no-one has seen this before, which isn't to say there isn't a
good reason, but it may be wise to check your client code, and also
perhaps check that there are no stack overruns anywhere.
Only other debugging hints I have are enable assertions, and there are
copious options in the low level drivers, generic eth drivers and net
stacks to enable extra logging.
