Thanks for the FLOWTABLE suggestion, wish I'd > remembered that one myself. :) Flowtable is one of the things in the network stack that I could think of that would do the sched_bind() dance. Thinking of the above in the context of 'but nothing else' it could really be anything. The pointer printed there is a struct thread *. show allpcpu show thread show thread <address given> bt will probably be a good start. I hope you have a serial console. Try to get a coredump as well if you can. /bz -- Bjoern A. Zeeb You have to have visions! Stop bit received. Insert coin for new address family.
